how do I setup a while loop and prompt user to read 2 variables

while ((($foldername = Read-host "name of folder to create? - Type Q to quit") -ne "Q")

($location = read-host "what is the Datacenter location? - Type Q to Quit) - ne "Q")) {

......

}

What is missing?  What are the rules of a successful entry of variables?

while((-not $foldername) -or (-not $location){
    $foldername = Read-host 'name of folder to create? - Type Q to quit'
    if($foldername -eq 'q'){exit}
    $location = read-host 'what is the Datacenter location? - Type Q to Quit'
    if($location -eq 'q'){exit}
}

thank you
