hi all ,
i want to access a form(name as form2) include in an iframe. so the "opDetails" is the name of the iframe.

var frameName = window.frames['opDetails'].window.form2.elements.length;

this cord segment is working in explorer but it does not work in firefox..

so please any one can explain the reason and the solution for this problem..?
