Hi Rahul,
Quickest way to get this resolved is to send a mockup page that reproduces the issue (you'll find our demos work in Chrome).
Otherwise, we can try to figure it out slowly - let's start with JS errors, do you see anything logged in the F12 tool's console? It might be in the F12 tool opened for the main window, or the popup window.
Best
Jim
