I want to calculate a newly added field with a created variable and an existing field. Here is the screenshot.



enter image description here



I create a new variable named "Sum_Area" and want to calculate a field "rate" with field "SUM_Shape_Area" divided by "Sum_Area". But the calculate field management does not work. Could anyone tell me where I am wrong? Really appreciate all kinds of help.
