I new to ME and am currently trying to create a macro that will pull numbers from a list in excel and place them into the correct field in another program. The program that I am entering the information into contains a pull down menu. There are 2 choices where the information could go. If there is nothing in the drop then menu than the program will need to create a new note. If there is a pre-existing popup in the pull down menu I need the program to recognize it and place the information into it. I am having troubles creating an If statement for this. How can I make this happen? Thanks
