I need to pass a variable into the following command, but I can't get it to work:

Get-Content E:\web.config ) | ForEach-Object {$_ -replace '<add key="DataSource" value="TEST_xxx" />', '<add key="DataSource" value="TEST_$num" />'} | Set-Content E:\web.config

Open in new window

$num is defined as LOT1

Any ideas ?
