If Statment help

[leo712]

Hi I'm fairly new to filemaker pro. I need to have a field auto complete when another is filled. I have a field that has status and a drop down list. And another which is a ticket number. I want filemaker pro to create a ticker number when status is filled in, but filled in with the words complete.

Thank to who ever can help me.

Here's a link to my file if I confused you a little.
