hide zeros and NA#'s from result of Index/match formula

Hi Guys and Gals...new to the forum and I have excel question:

Here is my formula: =INDEX(Demand!$A$4:$Y$121,MATCH('GMT 900'!$C7,Demand!$A$4:$A$120,0),MATCH('GMT 900'!BL5,Demand!$A$4:$Y$4,0))

How can I use a nested statement to hide zeros and NA#'s which may result? I'm getting NA#'s because some of the numbers being searched for in the first match function do not exist. The data on the sheet being indexed changes from day to day.

Thanks in advance for your help!

Worked great..thanks! (I had to change the "" to 0 because the cell is referenced in another calculation which resulted in an VALUE error from the blank cell...but the zero did the trick!
