Adding new options causes issues - powershell

Question

I have been able to create and frankenstein a menu to help me as IT support and am still learning powershell to read and write it proficiently but am confused why if I put more options I run into issues mainly at the end.

Write-Host -Object 'Q. Quit'
Write-Host -Object $errout
$Menu = Read-Host -Prompt '(0-5 or Q to Quit)'
switch ($Menu)
{

{
$Computer = Read-Host Please Enter Host name
Get-WMIObject Win32_NetworkAdapterConfiguration -Computername $Computer | `
