>>Hello, I am having a problem with a listbox click event returning the value of what is in the clicked item. I have rowsource as a select statmentand rowsourcetype as sql. It always returns the first record though. :(
>\
So it's a manual thing? I have to provide my own code to capture the value of what was clicked on?
