Pass variable to subscript

Question

I have a simple script in PowerShell with a list and a Job

$file_bme1 = "C:\file1.txt"
$file_bme2 = "C:\file2.txt"
$scriptList =@(
    'C:\Program Files\PuTTY\collection1.ps1'
    'C:\Program Files\PuTTY\collection2.ps1'
);
sleep -seconds 10
Write-Output "Script starting..."
foreach ($i in 1..1){
Write-Output "Loop $i"
$jobs=foreach($script in $scriptList){
    Start-Job -ScriptBlock {& $using:script}
    }
$jobs | Wait-Job | Receive-Job 2>$null
Write-Output "End of Loop $i"
sleep -seconds 30
}
Write-Output "Script completed."

I would like to pass variable $file_bme1 and $file_bme2 to the subscripts (collection1.ps1 and collection2.ps1), but I'm having issues on how to achieve that. Any recommendation?
