return a blank cell instead of a zero when using the = sign to match cells.

Guys this is probably so basic, but I cant get it.

I have a column of data of which I am using the '=' to match that data in another cell (if cell A2 contains '123', then cell D2 shows '123').

But when there is no data in the cell, it returns a '0'. I want it to return a blank cell instead of a '0'.

Thanks for looking.

That's the one! Thanx vlady!
