joomla calendar function popup box

Question

I am trying to get a calendar function to work:

 <label id="jform_issuedate-lbl" class="hasTip" title="Issue date::" for="jform_issuedate">Issue date</label>
 <input id="jform_issuedate" type="text" value="2013-09-25" name="jform[issuedate]" title="Wednesday, 25 September 2013">
 <img id="jform_issuedate_img" class="calendar" alt="Calendar" src="/media/system/images/calendar.png">

However when I use it in the site there is no pop up and no error is thrown. It was working and now isn't. I'm sure I must be doing something stupid and help appreciated

Answer 1

I found the problem

I had this in before another bit of script and it seems it isn't compatible with the calendar function in joomla 2.5
