Hi all
I have a DropDownList on a form, and I need to make a text box manadotory when one of three options is chosen from the DropDownList . 
And also possible incluse this within the validation summary when the button submit is selected.  
 Is this possible?
Can anyone please assist me with this code or point me in the right direction.  As I really struggling with it
