PROBLEM NOW SOLVED

I'm just trying to get a value from a checkbox with javascript for a price for an automatic price calculator.

-------
eg-<input type="checkbox" id="advert01" name="advert01" value="yes">


--------
I tried getting the value a number of ways but doesn't seem to work

i've tried - var checkboxValue = document.formname.advert.value

also

if (document.formname.advert.checked) {
checkboxValue = "300";
} else {
checkboxValue = "10";
}

but the value always comes up as 10. I also tried the ischecked function.

I've search google. can't find anything. I lost an hour today at work trying to sort this out. I've already got the info from about 50 text fields and 10 dropdowns. I just can't do it for the check box.

Can anyone enlighten me.

document.formname.advert.checked

have you tried using

document.formname.advert01.checked

????

yes. I had ment to write document.formname.advert01.checked


I was being really stupid. - PROBLEM NOW SOLVED
