Search Specified Range And Hide Zero Values

I am familiar with the custom formatting option to hide cell contents when you don't want them displayed in either a chart or when printing: Custom > Type > ;;

I was trying to create a macro that will search a specified range and whenever there is either a zero or nothing displayed in the cell (even though a formula exists), I want to custom format the cells to not be displayed.

My range is Range("B5:I16")

I tried to create something like

Code:
Dim dataRange as Range
Set dataRange = Range("B5:I16")
For each Cell in DataRange
if Cell ="" then Selection.NumberFormat = ";;"

I'm struggling to figure out how to tell Excel to step through each cell in this range, evalaute whether there is a blank and if so, apply the NumberFormat ";;" to it, otherwise let it be.
