Depends on what you mean by "simple". It will just take a few lines of code.
The difficulty lies in knowing which lines. Going "ballistic" in frustration is never helpful. Take this one step at a time. Make sure you can call your function when the pop-up opens. Make sure you have the value you want to set the combo box to at that point. You have not shown us much code, so we can't really say what is wrong.

Are you telling me that there is no simply way to have a user pick a value from a popup then redisplay that value in the popup if he goes back to the record again later? Is this a joke or a programing language? Somebody forgot to include an event that says if this record has a value show it in the popup? No you got to be pulling my chain. If you are not then this is a useless joke. Its an everyday need.
