Hello!
I'm sure this is a simple issue, but it's stumped me.
I'm new to python, please help me.
I have calculated two equations from two fields without any problem.
When I calculate the third equation using the results of the first,
an error occurs: Error 000539: Invalid Field . Failed to execute (CalculateField).
I don't know what to do in this case.
here's my code.
--------------------------------------------------------------------------
import arcpy
# Set environment settings
arcpy.env.workspace = arcpy.GetParameterAsText(0)
# arcpy.env.workspace = "D:\DocEnergy\DATA\BATIMENTS.gdb"
# ----------------------------------------
DDD = arcpy.GetParameterAsText(1).replace(',', '.')
DDDF = float(DDD)
fc = arcpy.GetParameterAsText(2)
# fields
CHAMP1 = arcpy.GetParameterAsText(3)
CHAMP2 = arcpy.GetParameterAsText(4)
# --------------------------------------------------
# EAUATION ET FORMULES
RESULTA1 = "!{0}!*!{1}!+{2}".format(CHAMP1, CHAMP2, DDDF)
RESULTA2 = "!{0}!*!{1}!-{2}".format(CHAMP1, CHAMP2, DDDF)
# how can I calculate this equation from the two equations RASULTA1 AND RESULTA2 ?
RESULTA = "!{0}!*!{1}!".format(RESULTA1, RESULTA2)
# Input the name of the field to be created
CHAMPS = arcpy.GetParameterAsText(5)
# Add field
arcpy.AddField_management("BATI", CHAMPS, "float", 20, 10)
# CalculateField
arcpy.CalculateField_management("BATI", CHAMPS, RESULTA, "PYTHON")
-------------------------------------------------------------------
thank you !!
