How to copy a row from one sheet to another if the number a column D1 greater than 0

Hello,

I am looking for a little help.

I am building a stock system for our stores that needs to be in excel.
I am getting quite far a head now but i need help on this on.

The is a worksheet for every staff member (up to 40) within each sheet are 30 odd rows of kit when they sign out some kit column D will be populated with how much of this kit they are borrowing. If they still have kit outstanding there will be a number in column D with the amount they have. I would like to copy this row to sheet ("Kit Outstanding") until the kit is returned.

File attached of what i have done so far.

Thanks Gordon
