Automatic Replication

Hi once again.

This time I have a sheet that holds some simple details, but for the less gifted PC users, I need a command button to perform a replication function, but unfortunatley, I'm not that skilled with programming.
There's a screenshot attached, but one of the cells has a Vlookup function in it.
I need the Vlookup to be replicated as well (onto a new row when the button is pressed). Also, when the row is replicated, it would be useful if all of the cell contents were empty to let new records be put in.

One last thing...I've made these style of buttons before (New Record). But whenever I actually press it with the code in, the button itself moves to a random position on the page... I have no idea why, but it isn't exactly useful.
Any ideas on how to stop it?

Please help!....again...

Cheers.
