return value from function with combobox - winforms

Question

I have a small GUI that will connect to a vCenter in a list. The forms open in the order I want, but I can't carry values between them. I've tried so many return calls I don't know what else to do.
Here is the code. Basically, the first form opens and asks for which vCenter you want. Then prompts you to authenticate (this all works wonderfully). But the problem comes in after the script is done. I don't get any return values.
function Connect-Vc ($vcArg)
{
$Form2 = $null
$selectedVC = $vcArg.selecteditem
$viconnection = $null
if ($global:defaultviserver -ne $null)
{
Disconnect-viserver * -confirm:$false
}
$clusterselection = $null
$DropDownTo = $null
$credential = Get-Credential -Message "Please Enter Elevated Credentials To Access $selectedVC. You can enter assuming you're an administrator on $selectedVC."
$username = $credential.Username
$password = $credential.GetNetworkCredential().Password
$viconnection = connect-viserver $selectedVC -User $username -Password $password
