Hi I've got two test environments, on one the Select operation works fine on the Combobox, on the other for the same value I want to select it wont work. It WILL work for certain other values in the combobox - why would this be? I've had to change the function to do a loop through the entire contents of the combobox looking for the value I want and that works fine in both environments,but is very slow. Can anyone tell me why the select operation wont find value? I checked to make sure no extra spaces and exact match (and must be exact match for the loop function to find and choose that same value). I nearly bald from tearing my hair out!
