Question

So, I will ask one of you geniuses on here for some help, as im sure someone will be able to work out what im trying to do...

I have a html table 

    <body>
<div id="style">
<div class="disktext">
</p>
 <table width='190' border='0' cellspacing='0' cellpadding='1'>
        <tr><td BGCOLOR='#0066FF'><font color='white'>Disk Space</font></td></tr>
        <tr onclick="toggleNextRow(this)"><td BGCOLOR='#FFFFFF'`enter code here`><?php echo $drive1;?>\<?= $freeSpaceC ?> (of <?= $totalSpaceC ?>)</td></tr>
        <tr class="hiddenRow">
            <td bgcolor='#FFFFFF'>
                <div class="disk">
                    <div class="used" style="width: <?= $barWidthC ?>px"><?= $diskStatusC->usedSpace() ?>%&nbsp;</div>
                </div>
            </td>
        </tr>
        <tr onclick="toggleNextRow(this)"><td bgcolor='#FFFFFF'><?php echo $drive2;?>\<?= $freeSpace1 ?> (of <?= $totalSpace1 ?>)</td></tr>
        <tr class="hiddenRow">
            <td bgcolor='#FFFFFF'>
                <div class="disk">
                    <div class="used" style="width: <?= $barWidth1 ?>px"><?= $diskStatus1->usedSpace() ?>%&nbsp;</div>
                </div>
            </td>
        </tr>
        <tr onclick="toggleNextRow(this)"><td bgcolor='#FFFFFF'><?php echo $drive3;?>\<?= $freeSpace2 ?> (of <?= $totalSpace2 ?>)</td></tr>
        <tr class="hiddenRow">
            <td bgcolor='#FFFFFF'>
                <div class="disk">
                    <div class="used" style="width: <?= $barWidth2 ?>px"><?= $diskStatus2->usedSpace() ?>%&nbsp;</div>
                </div>
            </td>
        </tr>
        <tr onclick="toggleNextRow(this)"><td bgcolor='#FFFFFF'><?php echo $drive4;?>\<?= $freeSpace3 ?> (of <?= $totalSpace3 ?>)</td></tr>
        <tr class="hiddenRow">
            <td bgcolor='#FFFFFF'>
                <div class="disk">
                    <div class="used" style="width: <?= $barWidth3 ?>px"><?= $diskStatus3->usedSpace() ?>%&nbsp;</div>
                </div>
            </td>
        </tr>
        <tr onclick="toggleNextRow(this)"><td bgcolor='#FFFFFF'><?php echo $drive5;?>\<?= $freeSpace4 ?> (of <?= $totalSpace4 ?>)</td></tr>
        <tr class="hiddenRow">
            <td bgcolor='#FFFFFF'>
                <div class="disk">
                    <div class="used" style="width: <?= $barWidth4 ?>px"><?= $diskStatus4->usedSpace() ?>%&nbsp;</div>
                </div>
            </td>
        </tr>
        <tr onclick="toggleNextRow(this)"><td bgcolor='#FFFFFF'><?php echo $drive6;?>\<?= $freeSpace5 ?> (of <?= $totalSpace5 ?>)</td></tr>
        <tr class="hiddenRow">
            <td bgcolor='#FFFFFF'>
                <div class="disk">
                    <div class="used" style="width: <?= $barWidth5 ?>px"><?= $diskStatus5->usedSpace() ?>%&nbsp;</div>
                </div>
            </td>
        </tr>
        <tr onclick="toggleNextRow(this)"><td bgcolor='#FFFFFF'><?php echo $drive7;?>\<?= $freeSpace6 ?> (of <?= $totalSpace6 ?>)</td></tr>
        <tr class="hiddenRow">
            <td bgcolor='#FFFFFF'>
                <div class="disk">
                    <div class="used" style="width: <?= $barWidth6 ?>px"><?= $diskStatus6->usedSpace() ?>%&nbsp;</div>
                </div>
            </td>
        </tr>
    </table>

What Im trying to do is use a php variable to define if a certain row should be displayed "built"

so the following is the if statement i am using, and this works, but I can't work out how to use it in this state.. 

    if ($drive1visible > "0") {
    try {
}

I want to take lines of the table eg 

<tr onclick="toggleNextRow(this)"><td bgcolor='#FFFFFF'><?php echo $drive2;?>\<?= $freeSpace1 ?> (of <?= $totalSpace1 ?>)</td></tr>
        <tr class="hiddenRow">
            <td bgcolor='#FFFFFF'>
                <div class="disk">
                    <div class="used" style="width: <?= $barWidth1 ?>px"><?= $diskStatus1->usedSpace() ?>%&nbsp;</div>
                </div>
            </td>
        </tr>

And make it so that the line is only created if the variable condition is met I have tried 

 if ($drive1visible > "0") {
        try {
<tr onclick="toggleNextRow(this)"><td bgcolor='#FFFFFF'><?php echo $drive2;?>\<?= $freeSpace1 ?> (of <?= $totalSpace1 ?>)</td></tr>
            <tr class="hiddenRow">
                <td bgcolor='#FFFFFF'>
                    <div class="disk">
                        <div class="used" style="width: <?= $barWidth1 ?>px"><?= $diskStatus1->usedSpace() ?>%&nbsp;</div>
                    </div>
                </td>
            </tr>
}

but it doesn't work...

Hope someone can help me, or tell me its not possible, Thanks so much!

UPDATE -

here is the whole file I am trying to make the modifications to..hope this helps..

You tried in a wrong way .. Try this .. 

<?php if ($drive1visible > 0) { ?>
<tr onclick="toggleNextRow(this)"><td bgcolor='#FFFFFF'><?php echo $drive2;?>\<?= $freeSpace1 ?> (of <?= $totalSpace1 ?>)</td></tr>
            <tr class="hiddenRow">
                <td bgcolor='#FFFFFF'>
                    <div class="disk">
                        <div class="used" style="width: <?= $barWidth1 ?>px"><?= $diskStatus1->usedSpace() ?>%&nbsp;</div>
                    </div>
                </td>
            </tr>
<? php  } ?>
