Select widget not keeping selected value

I ran into an issue today trying to prototype a select widget. When I run the process the dropdown select has the values correctly, but when I select one it doesn’t keep the value selected. What would cause that?

Ok, for those that are having the same issue. Remember you have to assign the selected value to something or it will not show. I created a variable and put the variable name in the value box on the right. I am using 7.2 UI designer.
