Still not working.

I've tried everything and I can get the information to populate in the user's profile. This is the code I'm using in the modifyprofile template:
<input type="radio" name="ncm" value="yes" $ncmnotchecked> yes
<input type="radio" name="ncm"value="no" $ncmchecked> no
I've changed the data type in the database to varchar(4) since I want a "Yes" "No" to appear in the user's profile.
For some reason, I just can't get it to work. Each time I check off yes or no in the Edit Profile, and go back to the page, it show the options as being unchecked. Any ideas?
