VBA for Excel - Selection returns “Compile Error: Expected Function or variable”

Question

So I've been messing around with some VBA code and I am trying to apply a border to a range of three cells. When I record the code using the VBA recorder built in to Excel I get this back:

Range("A1").Select
ActiveCell.Offset.Range("A1:A3").Select
Selection.Borders(xlDiagonalDown).LineStyle = xlNone
Selection.Borders(xlDiagonalUp).LineStyle = xlNone
With Selection.Borders(xlEdgeLeft)
    .LineStyle = xlContinuous
    .ColorIndex = 0
    .TintAndShade = 0
    .Weight = xlThin
End With

And so on with the other sides.

My issue is that as soon as I try to run the code again it stops before executing anything, highlights the first selection (in the blue active text way, not the yellow step into way), and opens a message box saying "Compile Error: Expected Function or variable". I've looked at my other sections of code that I've already written and they are also having this problem now, which I don't think they were doing yesterday.

I'm trying to figure out if I clicked a wrong button yesterday or what but my code is completely unusable now for some reason.

Answer 1

Just a guess, but if you go to Tools > References, are there any that are checked that say "MISSING"? If so, try unchecking the reference. I'm not sure why, but I've come across that in the past where a missing or lost references makes otherwise-normal code behave wacky.

I don't see anything obvious but you can revise this a bit from the "recorded" version:

With Range("A1:A3")
    .Borders(xlDiagonalDown).LineStyle = xlNone
    .Borders(xlDiagonalUp).LineStyle = xlNone
    With .Borders(xlEdgeLeft)
        .LineStyle = xlContinuous
        .ColorIndex = 0
        .TintAndShade = 0
        .Weight = xlThin
    End With
End With

Answer 3

Due to high memory usage, I turned something off in my Excel; since then, memory usage is very low (in hundreds MB instead of GB). I'm pretty sure this feature turned off has something to do with it.
