I need this to be required but ONLY if the drop down is set to YES.. I can't add a validation rule to either the section or the list box ... I have also tried using a trigger (setting a text box to 1 if a value is selected, but this only works one way - when a value is selected in the list box, it changes the trigger to 1, but I can't get it change back to 0 when no values are selected) --- I hope this makes sense, I have researched and have not found an easy way to accomplish this - Any help would be much appreciated! Thanks! -Andrew
