CSS Modification and Facebook Application Upload

I need assistance in modifying some CSS/ HTML programming code (minor modifications) and integrating that CSS into the Wildfire Application to be used in a Facebook user generated video contest. Essentially this is the graphic design element for a Facebook Page application that needs to be integrated into the Wildfire program. The instructions for the app/ upload are here [login to view URL] We are doing a video contest using a custom CSS layout, its the "white label" option. I need to get this done today/ tonight for launch tomorrow. I have the code already mostly finished, just need to make a couple of minor changes and get it uploaded...I am not very technical and my programmer flaked...the person who takes this project needs to be patient and committed to getting this done right today/tonight.
