Function question.

Hi Guys,

I just have a quick function question.  I'm getting in the habit of compartmentalizing my scripts into functions, and I'm running into a small issue.  I'm trying to pass a variable back out of that function and make it accessible by other functions and script items.  Here is an example :

function Get-Chassis {
cls
Write-Output "Getting chassis type of current system..."


	switch ($chassis){
	"1" { $systemtype = "VM" }"3" { $systemtype = "Desktop" }"8" { $systemtype = "Laptop" }"9" { $systemtype = "Laptop" }"10" { $systemtype = "Laptop" }"11" { $systemtype = "Laptop" }"12" { $systemtype = "Laptop" }"14" { $systemtype = "Laptop" }
	DEFAULT {$systemtype = "Other"}
	}

Append-LogContent "Current system is $systemtype!"

}

I am just trying to have this function as a tumbler for some post image apply options but for that to work, I need it to pass $systemtype back to the main post-apply script.  Right now it's stuck in that function only.  Help would be appreciated :)  Thanks!
