Problem in filing service tax return

Dear Sir/Madam,

What exactly revenue means? Whether service tax or others. And when this columns is to be filled. We paid service tax belongs to 2006-07 and 2007-08 now. Which period tax have to be filled here? For arrears also we have to file 4 different ST 3 challans or we can file in one challan.

Its urgent. Please help me.
