subscript used on non accessible variable

[great77]

I have a script which was working for months. But somehow is throwing this error  

"subscript used on non accessible variable"

ReDim $aArray2D[$aArray[0]+1][2]
ReDim $aArray2D[$aArray^ ERROR

I used the Ubound but still not workinbg. How can I used uBound  on this For  $i = 1 TO Ubound ($aArray[0]) - 1 . It seems am not getting around this and why this error when it was working before.

Global $spath = "C:\Automation\Air_List\unassigned"
$Extract = "C:\Automation\Air_List\urgent"
$checkpath = StringRegExp($spath,"^.+\\$",0)
If $checkpath = 0 Then $spath = $spath & "\"
$aArray = _FileListToArray($spath, "*.RDF", 1)

Global $aArray2D[10][2]
ReDim $aArray2D[$aArray[0]+1][2]
$aArray2D[0][0] = $aArray[0]
sleep(100)
For $i = 1 TO $aArray[0]
    $aArray2D[$i][0] = $aArray[$i]
    $aArray2D[$i][1] = FileGetTime($spath & "\"  & $aArray[$i],1,1)  ;;;0=Last modified, 1=created, 2=last accessed  FileGetTime ( "filename" [, option = 0 [, format = 1 return string and 0 rerturn array]] )
Next
_ArraySort($aArray2D,1,1,"",1)

great77,

Where is the error-checking to confirm that you have a valid array returned by the _FileListToArray call before trying to access it?

I assume that _FileListToArray returns an error and hence does not create $aArray.
So check for an error after callung _FileListToArray.

Edit: Too slow

I did not do that. How will I do that ? Thanks for your time

Example:

$aArray = _FileListToArray($spath, "*.RDF", 1) 
If @error Then Exit MsgBox(0, "Error", "_FileListToArray returned @error = " & @error)

Thanks Water  and Melba23. Now I understand the array is not returning anything. That was why it was giving the error.
