jimhnet author I have a screen with 5 items on it and I only want to allow the user to select any two of them. How would you best handle it. Thanks Jim

	Jim, the one of the easiest way to limit number of items is to use Before record added event. Here is a sample code: if (($values["item1"]!="" and $values["item2"]!="") or ($values["item1"]!="" and $values["item3"]!="") or ($values["item1"]!="" and $values["item4"]!="") or ($values["item1"]!="" and $values["item5"]!="") or ($values["item2"]!="" and $values["item3"]!="") or ($values["item2"]!="" and $values["item4"]!="") or ($values["item2"]!="" and $values["item5"]!="") or ($values["item3"]!="" and $values["item4"]!="") or ($values["item3"]!="" and $values["item5"]!="") or ($values["item4"]!="" and $values["item5"]!="")) return true; else return false; Also you can limit number of items on the fly using custom JavaScript code.
