should be - any suggestions?
Excactly, and why do you say it should be passing the formname if you use
this.form in an image?
The keyword 'this' should only be used if you knwo WHAT it is refering to.
eg: If you use it in an input type="text" it will reference that
inputelement.
If you use it in an image....
Solution: simple give your form a name, and pass that to the function.
From your function you can use:
function update(formname) {
var formref=document.forms[formname];
var mon=formref.mon.value;
alert(mon);
}

That is no reason to leave the names of the forms out. :-)
Good luck!
