enter 4 colums of data in a row then shift after hitting enter

Hi,
I really know nothing about vba so here goes. I would like to enter data in a row with 4 cells of info. then hit enter and return to the first cell and move the row down. all four cells must have data entered. and all four must move down. i tried some code as below i found and i modified but it did not work as expected. this moved the row down when returning the cursor to A2. It also should not copy the data style of the top row. Whats the best way to do this ?? Any help would be appreciated. post corrected i think. cheers

cheers Mark
