How to redim a two dimensional array [RESOLVED]

[Chris H]

I'm trying to resize a two dimensional array while preserving its contents in VBScript but it crashes with a Type Mismatch error. For some reason on my Redim statement it doesn't like the X variable. Can anyone tell me why, or what it is I'm doing wrong? A regular Redim statement works fine with the X.

X=0
Set FS  = CreateObject("Scripting.FileSystemObject")
Set inFile= FS.GetFile("test.txt").OpenAsTextStream(1, -2)
Do While Not inFile.AtEndOfStream
    Redim Preserve arrLines(X, 12)
    tmp = inFile.Readline
    X=X+1
Loop
inFile.Close
