Hi, I've been struggling with coding this form for many days. I hope someone can point out to me what went wrong. If a person leaves a blank, then an error message will appear. However, if I didn't enter anything, 2 similar messages appear, which is what I don't want. I only want error message to appear if it is blank or if the data does not conform to the regular expression. Also, I'm not so how to validate the radio button. please please help me.
