Hi,
I've to calculate a field based on another field in a joined table, but an error occurs:
"Parameters are not valid.
ERROR 000728: Field !Table_A.field_A! does not exist within table"
Both tables are in the BASELINE.gdb. The Join occurs without any problem.
Please, any help appreciated.
Thanks in advance

import arcpy
from arcpy import env
env.workspace = "C:/TMP/BASELINE.gdb"
Table_A = "dist"
Table_B= "matrix"
arcpy.AddJoin_management(Table_A, "id_grid", Table_B, "id_matrix")
arcpy.CalculateField_management(Table_A, "!" + Table_A + ".field_A!", "!" + Table_B + ".field_B!","PYTHON")Please, any help appreciated.
