option button - n/a

[teiben]

I'm working on a survey database, I'm having the users select the opton button to rate (1 - 10). Then as an after thought, I thought I would add a button that says N/A or doesn't apply. Course option buttons store numbers.

ANy idea's on how to accomplish this? What ever value gets stored I wouldn't include it in the results.

Couldn't you just assign N/A a number, like 11? and then whereever it's going to be displayed have it switch to N/A if it's 11.
