Dynamic Add Row

Dynamic Add Row

I have this script that I'm trying to customize that will allow me to dynamically add rows of data. Other than adding rows of data it should allow me to add a block which contains an addrow button to add dynamic data within each bloc. Please view the following link in IE, for some reason FF is not working right. I need a few functions written and would be willing to pay someone to work on it for me if there is in an interest in doing so.

Thanks you in advance!
