[naveen51]

Hi.I am very new to Browser compatability testing using QTP 11.
we have written vb script to test web application on IE8. I would like to know how we can make use of this existing code or convert so that it works fine in the other browsers like Firefox,chrome and Safari(After installing the necessary patches).Please let me know possible issues with this way.

Make sure that you haven't used any DOM methods in your scripts, which may not work on across all the browsers (as the DOM is different in each browser).
Will post you the detailed guide lines for this shortly.
