The user digitizes a polygon and with the record selected it adds attributes to the record with a toolbox. The script works well without the 5th parameter (PlanEQIP) but I get a strange error message when I have this parameter. Does anybody know what the problem would be? Would it be because the field is short integer but the parameter data type is set to long?Thanks!Here is part of the code:################################################## # #Script: Attribute Table for reporting (Stewardship) # ################################################## #Import modules import os, sys, arcpy, traceback, arcgisscripting #Set Map Document mxd = arcpy.mapping.MapDocument("Current") #Set Overwrite Option arcpy.env.overwriteOutput = True df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0] gp = arcgisscripting.create(10.1) #del row #del rows try: #Sets parameters (attributes) Status = gp.GetParameterAsText(0) Office = gp.GetParameterAsText(1) Forester = gp.GetParameterAsText(2) DateStart = gp.GetParameterAsText(3) PlanEQIP = gp.GetParameter(4) StatusDomain = {'Completed': 'C', 'Pending': 'P'} StatusCode = StatusDomain[Status] officeDomain = {'Alpine': 'AL', 'Austin': 'AU', 'Carthage': 'CA', 'Corpus Christi': 'CC', 'Conroe': 'CO', 'Crockett': 'CR', 'Crockett':'CR', 'College Station': 'CS', 'Canyon': 'CY', 'Dallas': 'DA', 'El Paso': 'EP', 'Fort Worth': 'FW', 'Gilmer': 'GI', 'Granbury': 'GR', 'Hamilton': 'HA', 'Henderson': 'HE'} officeCode= officeDomain[Office] foresterDomain = {'Brittany Compton': 'bcompton', 'Brian Pope': 'bpope', 'Buster Robinson': 'brobinson', 'Clay Bales': 'cbales', 'Daniel Duncum': 'dduncum', 'Daniel Lewis': 'dlewis'} foresterCode = foresterDomain[Forester] #Create Update Cursor #Create Update Cursor #This pre with arcpy.da prevents data locks.
