I'll begin by stating I am very new to the python world! 

My problem is this....


I am trying to use field calculator in ArcGIS Pro to return a calculation of values in other fields based on an if statement, if that makes sense! Not sure if it can be done?


The Calculation is 



Basically thus;




Code Block

def weightAADT(rp, Qs, Ls):
       if rp=="Urban Two Lane":
            return sum(Qs * Ls) / sum(Ls)


my error is "TypeError: 'float' object is not iterable"


Any help appreciated
