Scala Increment Counter on calling Function

How to increment a function each time its called in scala? I have a function A which performs a set of actions, when a user calls the function A, i would like to have a counter which increments and returns the counter value. The below code doesnt return the expected counter of 1 when i call it.

def return_id (email_user: String) : Int = {
    Thread.sleep(1000)
    val count = 0
    implicit val conn = ExecuteQuery.getConnection(GENERAL_DB, DB_USER, DB_PASS)
    var idQuery=executeQuery(s"SELECT id FROM Profile WHERE email = '$email_user';")
    idQuery.first()
    val pid=idQuery.getInt("id")
    println(pid)
    if(pid != 0){
     +count = 1
    }
    return count
   }
