Validate Form - make drop down required based on radio button
Wondering the best way to set up a drop down box to be required if a radio button has been selected.
On this form
https://www.tmcc.edu/admissions/downloads/degree-and-emphasis-change/
near the bottom we have 4 radio buttons and 4 drop down boxes. Want to make the drop down be required if the radio button by it is picked.
Any help would be greatly appreciated.
