Recursive function can't call itself

Hey guys,

I have this script that selects a site from all the sites created in an IIS server:

Param($webServers,$cred)


# -----------------------------------------------------------------
# --------------------------- FUNCIONES ---------------------------
# -----------------------------------------------------------------

# Con esta funcion me conecto server por server en SelectSiteInAllServers

Function SelectSite ()
{
	Import-Module WebAdministration
	
	$count = 1
	$name = gci IIS:\Sites

	foreach ($n in $name) {
		Write-Host $count " - " $n.Name
		$count += 1
	}

	Write-Host ""

	# Entra en un loop hasta que de una opción correcta
	$opt = $null
	while ($true)
	{
		[console]::ForegroundColor = "Yellow"
		$string = Read-Host -Prompt "Ingrese el número"
		[console]::ResetColor()
		if ([int]::TryParse($string, [ref]$opt) -and $opt -lt $count -and $opt -gt 0)
		{
			break
		}
	}	
	# Verifico que la opción elegida sea la que quiero actualizar
	$script:env = Out-String -InputObject $name[$opt-1].Name
	$script:env = $script:env -replace "`n","" -replace "`r",""
	Write-Host ""
	# Write-Host "Se seleccionó el site" `'$script:env`'"."
	$check = Read-Host -Prompt "Presione 1 si desea proseguir, o 2 si quiere volver a elegir"
	If ($check = 2)
	{
		SelectSite
	}
	Write-Host ""
	Return $script:env
}

Function SelectSiteInAllServers ($webServers,$cred)
{
	$script:res = "True"
	If ($script:res -ne "False")
	{
		# Creo mi conexión al server
		$s = New-PSSession -Name TempSession -ComputerName $webServers[0] -Credential $cred
		
		# Llamo a la función para crear los sitios
		$script:res = Invoke-Command -Session $s -ScriptBlock ${Function:SelectSite}
		
		# Cierro la conexión al server
		Remove-PSSession -Name TempSession
	}
}


# -----------------------------------------------------------------
# ---------------------------- PROCESO ----------------------------
# -----------------------------------------------------------------

CLS

Write-Host "|**********************************************************|"
Write-Host "|******************* Selección de Sitio *******************|"
Write-Host "|**********************************************************|"
Write-Host ""

$test = SelectSiteInAllServers $webServers $cred

Return $script:res

My problem appear when I run the recursive part of the script (this one):

If ($check = 2)
{
	SelectSite
}

Because it's telling me that it doesn't recognizes "SelectSite" as a function... It seems like a stupid error, but I can't find it! Is anyone seeing something I'm not? 

My brain is going to explode over here!

Thanks!
