Help with EXCEL

man what a boring thing, but i am stuck and getting kinda frustrated with this god forsaken program and here is my boggle.

from the picture as you can see i have 3 columns in coloum C i have a money value, column D is the column that i want to multiply it by and my boogle lies with column E.

i want to know if there is a way of getting rid of pointless $0.00 and having column E blank until i actually enter a multiple into column D.

god i hope this is a decent explaination…

thanks
