Pivot Table Calculated Field Error

Hi,

I am calculation a very simple formula of " Margin / Revenue" in <g class="gr_ gr_97 gr-alert gr_gramm gr_run_anim Grammar only-ins doubleReplace replaceWithoutSep" data-gr-id="97" id="97">pivot</g> table. But I keep receiving <g class="gr_ gr_159 gr-alert gr_gramm gr_run_anim Grammar only-ins doubleReplace replaceWithoutSep" data-gr-id="159" id="159">error</g> message. I jut figured it out that " Revenue" column is considered " Zero" in my workbook. I have double checked it in my raw data and " revenue' column is defined as the number for sure.

Can anybody help pls?

Regards,

Abbas,
