I have been going through the forum and trying everything. Maybe someone here can see where i have gone wrong.
I amd calculating the percent change and have come across only one of my properties with no value, which gives me the error of dividing by zero. So I am using if then else statements to avoid it. Here is the Pre-logic:
If [LVal2013] = 0 Then
Per1314 = 0
Per1314 = [Diff1314] / [LVal2013]*100
Where am I going wrong? FYI: Arcgis 10.2.2
