Topic: Simple viewer does not show in IE, it does in firefox?

I have been editing a simple viewer template from lightroom with dreamweaver, to include a header and footer since the template did not allow space for a menu bar. Most things work in firefox, but the gallery does not appear in IE, the spry works rather inconsistently too. everything worked fine on both browsers before the changes? I am pretty new to both softwares.
