Improved Order Form HELP Part II

**cardnexus** · 09-19-2006, 09:22 PM

I tried to mod the select menu to radio button for this order form. However, instead showing the value I assgined, it displays an error message.
Can anybody help me with this?

u need to name the form

Yes but it is not mandatory, you still can access the form fields using the following method

document.forms[number].elements[number]

Code:

document.forms[0].text.value = 'The new value';

If you name the form yes there won't be any confusion you can access the form directly using its name.

I added two For statements and the form name [] and it is still not working.
I can't really figure out why.

Can anybody help me?

Thank you!
