Powershell Calling Functions

Very odd issue as i have no idea why i can't call any of the functions as per the below.

CLS
#… Present the Menu Options
Write-Host “`n`tOffice 365 Connection`n” -ForegroundColor Red
Write-Host “`t`1. Connect To O365” -Fore Cyan
Write-Host “`t`2. Grant Full Access” -Fore Cyan
Write-Host “`t`3. Quit`n” -Fore Yellow
#… Retrieve the response from the user


$option = read-host "Type your choice"

IF ($option -eq 1){LoadMain}

Elseif ($option -eq 2){FullAccess}

Elseif ($option -eq 3){GetLost}

function LoadMain{
CLS
$user = “test@test.OnMicrosoft.com”
$cred = Get-Credential -Credential $user
Import-Module MSOnline
$O365Session = New-PSSession –ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell -Credential $cred -Authentication Basic -AllowRedirection
Import-PSSession $O365Session -AllowClobber
Connect-MsolService –Credential $cred

clear-host
write-host                        
write-host  -ForegroundColor white  "You are now connected to office 365 Shell"
    Write-Host
write-host  -ForegroundColor white  "Get-MsolUser -UserPrincipalName test@test.onmicrosoft.com | FL".

}
function FullAccess{
CLS
$adminaccount = Read-Host "Enter your full email address to provide access to"
$victimaccount = Read-Host "Enter full email address for the account you want access to"
$user = “test@test.OnMicrosoft.com”
$cred = Get-Credential -Credential $user
