PowerShell Looping Problem

[starlight849]

Hi,

I have two datatables that I'm attempting to loop through in a nested loop.
I am never able to hit in the second loop when I'm using a second datatable. However, if I store the information in an array then I'm able to hit the second loop.
I have ran tests to make sure the information is getting filled in both datatable so I know that isn't the problem.
If I do seperate ForEach loops, I am able to loop through both tables successfully. However, at this point, for my purposes I need to nest them.
Can anyone point me in the right direction?
Here is my code

 foreach ($iRow in $tableIns.Rows)
         { 
           Write-Host "<instance id=""$($iRow[2])"">";
         
            foreach ($rRow in $tableRev.rows)
            {
            Write-Host "hello";
            }
          }
