PowerShell Script Help needed

I have a PowerShell script that requires two inputs

I have it working sort of  just need some fine tuning from an expert.

I am passing the Event Id error number and then selecting which event log system or application

When the script presents the results I am returned to the beginning of the script
My problem is it does not go back to the beginning it goes to the second question

How can I incorporate the Read-Host and the MainMenu section?

I need to be able to enter the Event ID Error again

Here is my script

Clear-Host
$in = Read-host “Enter the Event Error”
function mainMenu()
{
	Clear-Host;
	Write-Host "====================";
	Write-Host "= Select Event Log =";
	Write-Host "====================";
	Write-Host "1. Press '1' for System Log";
	Write-Host "2. Press '2' for Application Log";
}
function returnMenu($option)
{
	Clear-Host;
	Get-WinEvent -FilterHashtable @{ LogName = "$ev"; id = $in} -maxevents 1 | FL *
	Write-Host "Press any key to return to the main menu.";
	$host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown");
}
do
{
	mainMenu;
	$input = Read-Host "Enter a number for an option or type `"quit`" to finish."
	switch ($input)
	{
		"1"
		{
			$ev = "System";
			returnMenu $input;
		}
		"2"
		{
			$ev = "Application";
			returnMenu $input;
		}
		"quit"
		{
			# nothing
		}
		default
		{
			Clear-Host;
			Write-Host "Invalid input. Please enter a valid option. Press any key to continue.";
			$host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown");
		}
	}
} until ($input -eq "quit");
Clear-Host;

Select allOpen in new window

I have gathered different code from searches I have found to get this complete

I hope I am not to far off

Feel free to modify this


Thanks in advance
