PowerShell Function to return a variable

I'm writing a function to create a variable called $Credentials which I use in another function to verify if it's valid or not. By using return $Credentialsin the function I hoped the variable would've been available after the Function Import-Password has ran, but this isn't the case..

I think this could be solved by using $script:Credentials, but I don't think it's needed if the function can output this variable.

Thank you for your help.

Function Import-Password

# Check the password file
Function Import-Password ($UserName,$PasswordFile,[switch]$SendMail) {
    try {
        if (!(Test-Path $PasswordFile)) {
            Write-Host "$env:COMPUTERNAME > Check password file: $PasswordFile > The password file can not be found`n
            - Password file :`t $PasswordFile
            - Server name   :`t $env:COMPUTERNAME" -ForegroundColor Yellow
            if ($SendMail) {
                Send-Mail "FAILED AD Authentication" "The password file can not be found" "- Password file : $PasswordFile<br>- Server name   : $env:COMPUTERNAME"
            }
            break
        }
        $Password = cat $PasswordFile | ConvertTo-SecureString -Force -ErrorAction Stop
        $Credentials = New-Object System.Management.Automation.PSCredential -ArgumentList $UserName,$Password 
        return $Credentials
    }
    catch {
        Write-Host "$env:COMPUTERNAME > Check password file: $PasswordFile > The password has been hashed with another account than the account used to run this script (all 3 users/owners need to be the same)`n
        - Script account:`t $env:USERDNSDOMAIN\$env:USERNAME
        - Password user :`t $UserName
        - Password file :`t $PasswordFile
        " -ForegroundColor Yellow
        if ($SendMail) {
            Send-Mail "FAILED AD Authentication" "The password has been hashed with another account than the account used to run this script (all 3 users/owners need to be the same)" "- Script account: $env:USERDNSDOMAIN\$env:USERNAME<br>- Password user : $UserName<br>- Password file : $PasswordFile"
        }
        break
    } 
}
Import-Password $UserName $PasswordFile

You have to capture the output of the function in order to use it later in your script e.g.:

$cred = Import-Password $UserName $PasswordFile
