This depends on your design.
Do you have 4 detail sections or 1 detail section and is there anything else on the row that is not null or blank?
The most basic way is to go into your Section Expert, highlight the section you want to suppress (this is probably your detail section) and there is a box for suppressing blank row. Check that off and now whenever your entire row is blank it will suppress it but display the next row.
I am guessing here but I have a feeling you put all 4 items in one detail section. If in the above examply you have stuck all 4 "lines" into 1 detail section, split it into 4 details (a,b,c and d) and place each item on a seperate detail section then use that suppress blank option on each of those sections.
Make sure you place the Name on Detaila, street on detailb, etc. as this is the order it will diplay in.
If this doesn't answer it for you please post a little more detail abot your report set up so we can help more.
