As per the subject line,
Firefox's error console says document.forms[0].submit is not a
function.
the javascript is
function makequery(param){
document.forms[0].qu.value=param;
document.forms[0].submit();
}
called by clicking on a link with a javascript url.
the value of qu gets changed correctly.
this same thing happens if I use the name of the form, which is main.
document.main.submit() is not a function.
