I have a python script which creates a join between two layers.
I am then trying to use calculate field to take the data from one column (DemandWeight) and adding it to another column. However, the other column is made up from a variable so cannot be hard coded. For example, I have a variable called weightedvalue made up from attributes from another table. So after the join I have NetworkLocations.weightedvalue. But the message I get is that is not an actual column name. it is looking for the actual enbedded coIumn name. I also tried NetworkLocations.%weightedvalue% but does not work either. The weighedvalue changes as per a loop.
Any ideas would be appreciated
