Filling in a VBScript array in a for loop

Question

I'm attempting to create and fill in a two-dimensional array in VBScript, which resides in an ASP page. I have the following code:

Dim array(11, 6)

For record = 0 To 6
    array(6, record) = 8
    array(7, record) = "test"
Next

array(6, 3) = 8
array(7, 3) = "test"

The for loop doesn't work, though. Nothing gets filled in. If I do it explicitly, like the code after the loop, that works just fine.

I've hardly ever used VBScript before but this seems like it should work. Why is my loop not doing anything?

It's a for loop; shouldn't that happen automatically? Even if not, the 0th element doesn't get filled in (and it doesn't loop forever). — Andrew

@ghostdog74 - no, "Dim a(11,6)" creates a 12 x 7 FIXED array. — Ekkehard.Horner

Your "doesn't work" doesn't work. You'll have to describe exactly what you expect and what happens instead. Otherwise -

Dim a(11,6)
For i = 0 To 6
    a(6,i) = i
    a(7,i) = "test"
Next
WScript.Echo a(6,0),a(7,0)
WScript.Echo a(6,6),a(7,6)

0 test
6 test

Is there an evil "On Error Resume Next" active?

WRT the OERN:

You could insert an "On Error GoTo 0" immediately before the critical/new code and continue driving with your eyes shut with an "On Error Resume Next" immediately after it.

Or: copy the new code into a clean/empty .vbs to be used by cscript.exe

Or: post the relevant part of the code completely.

Yes, there is an On Error Resume Next. I can't really do a whole lot in the way of error checking because this is embedded in an ASP page (code which hasn't been touched in 10 years, too).

I used an On Error GoTo 0 and received a "Variable is undefined" error. I shouldn't have to explicitly define each element in the array, right?

I would imagine that it's because record is not defined
