Change the formula to =IF(jan!e10<1,0,jan!e10/e2) you may need to adjust the
0 if you are working with smaller numbers.

I have a formula on one spreadsheet that uses data from other spreadsheets in
one workbook. The formula is =jan!e10/e2, and repeats down to =jan!e88/e2.
This equals a percentage. I am having trouble when jan!e10 is blank, it
gives me the #div/0! error, but when I try to do a conditional format, it
tells me that I cannot refer to cells on other spreadsheets. Is there
something I can do so it either shows a 0 or leaves it blank? Or even makes
the font white to match the background until a number is filled in?
