IF statement on a PowerShell Script

Hello, I am working on a script to check an Active Directory User Account status, if it is locked out.

And also I need to write an specific output.

I am Using Get-ADUser command , My script is as follow:

**********************
param
(
      [string]$user = ""
)

$command="Get-ADUser "+$user+" -Properties * | select-object LockedOut | findstr True"
$result=invoke-expression $command

if ($result -contains "True")
      {
      $state="CRITICAL"
      $exitcode=2
      }
      {
      $state="OK"
      $exitcode=0}

      Write-Host $state
      exit $exitcode
********************************

but I can´t get to work the IF statement, I have added an echo line to debug, and the result is the next:

********************************
