Microsoft VBScript Runtime error 800a001c

I was editing my website and added a feature in error. I tried deleting it
all to no avail. Then I began getting the following error message:
Microsoft VBScript runtime error '800a001c'
Out of stack space: 'Val'
/admin/content/pages.asp, line 7
The part in /admin/content/pages.asp, line 7 reads:
For I = 0 To UBound(arrArray)
If Val(arrArray(I)) = Val(varValue) Then
Array_Exists = True
Exit Function
End If
Next
Array_Exists = False
End Function
I have no idea what to do about it. Any hint or link to the right direction
will be appreciated.
Thanks.
