Why Is my "If Else" statement getting skipped? - powershell

Question

I am working on a script to allow my sys admins to make changes to an ACL without having to drill down to the folder level. So far, everything is executing as intended except for my first "If..Else" statement in my first switch. It gets skipped entirely and moves on to asking for the account name and I cannot figure out why.
Does anyone have any ideas?

Your if-else is working correctly as you have written it. What you have written, however, is not what you want.
First: In the Write-Host in the else clause, you do not want to use the escaped `r; you want to use an escaped `n, or perhaps nothing at all. `r indicates a return-to-start-of-line but not go-to-next-line; `n indicates return-to-start-of-line-and-go-to-next-line. The repeating of the entered path in green in your example above is a strong hint that that Write-Host is being executed.
Second, your Test-Path causes $test to have no value, because you are sending the results to the null device instead of allowing it to be returned to the statement for assignment to the variable. Remove the | Out-Null.
