I'm pretty new to all this. What I need to do is create an array of subnets, and if the IP address is not in a particular subnet then basically to exit the script. I've got most of it done, I just need to loop through the array of subnets and then do an if on each element in the array. Here's a code snipet:

It's grabbing the IP address fine and diong the subnet thing. All I need to do is loop through the allowedSubnets array and compared each iteration to the subnet variable. I've got it doing the loop, bu not the if statment. Do I need to do something like for i < allowedSubnets.elements.count blah blah blah ??

If I understand your situation correctly, then try this to see if it does what you want:

function checkSubnet()
   ip = GetIPAddress
   iparray = Split(ip, ".")
   iparray(3)="0"
   subnet = join(iparray,".")
   objWshShell.Popup subnet
   ' Now loop through the subnets and see if the logon script should run
   bIsAllowed = False
   For Each objItem in allowedSubnets
       If subnet = allowedSubnets Then
         bIsAllowed = True
       End If
   Next
    If Not bIsAllowed Then
      objWshShell.Popup "You are not permitted to map drives from this network"
   End If
end function

Um ... no, not quiet !! allowedSubnets is an array, which I declared at the start of the script. So I have
Dim allowedSubnets(2)
allowedSubnets(0) = "10.128.0.0"
allowedSubnets(1) = "10.129.0.0"

So with this line:
For Each objItem in allowedSubnets
...
Next

I was able to loop through the allowedSubnets array. But then I need to do an if statement on that particular iteration to find out if the subnet variable (which is the user's subnet) is equal to that particular iteration. If it is, then eventually I will just set a variable to True similar to what you've done (I was just putting in the popups for debugging purposes). But my if statement just says
If subnet = allowedSubnets Then
...
End If

I think it needs to say something like
If subnet = allowedSubnets(i) Then
...
End If
where i would be the iteration of allowedSubnets (so in this case either 0 or 1 because there's only 2 elements in the array). Does all this make sense? So escentailly I need to reference the current iteration, but maybe to do that I need to change my for loop to say For i = allowedSubnets.elements.count - or something like that, yes?? no?? any ideas??

Thanks in advance

Ooops...use this:

If subnet = objItem Then
