Urgent is not a good word to use on forums.

What is the error. You never mentioned what the error message was. What I do not understand is f3 is a variable so why are you referencing it as a form element?

Ajith,

I think f1, f2 values are selected values of two "select" options. To get the selected option of "select", use the following.

var f1 = document.formname.selectname.options[ document.formname.selectname.selectedIndex ].value;

var f2 = document.formname.selectname.options[ document.formname.selectname.selectedIndex ].value;
