Blank Space at bottom of form?

Hello,
I think this may be the result of using CSS positioning to achieve the result I want to get, but I figured I would ask here and maybe someone else has figured out how to resolve this.

I want to have a Event Creation Form with 2 Sections that display as 2 distinct columns. Left side would be Contact Info, Right side would be Event Info.

Ive been able to use the CSS Ready Classes to split fields into 2 columns but not entire sections and when I use CSS positioning to lay it out the way I want there is a large blank space at the bottom of my form before the Submit button is displayed.

Has anyone figured out a way to resolve this or work around it?

thanks so much,
Brian

unfortunately when I get frustrated, I went back to the drawing board and started over, so I don't have the local version I was working with...

This is the NON PUBLIC version of the form I am currently working on:

Ideally I would like the Contact Information to be on the left and Event Information to be on the right. Is there an easy way to make this happen?

Thanks again for your help!
