Problem in a Buton addin

ikbelkachbouri

I have created a button and I want that when a click a field in the attribute table is filled after having made a calculation but it does not work.

This is my code :

class ButtonClass1(object):

"""Implementation for Bouton_addin.button (Button)"""
def __init__(self):
self.enabled = True
self.checked = False
def onClick(self):
inTable = "Bati_Service"
fieldName = "tax"
expression = "getClass(float(tax))"
codeblock = def getClass(tax):
if (SUP < 100):
tax= (pourc_serv /100)* SUP * 2
elif (SUP > 100 And [SUP] < 200):
tax= (pourc_serv /100)* (SUP * 3.8 )
elif (SUP > 200 And ^{< 400):
tax= (pourc_serv /100)* (SUP * 5.4 )
elif (SUP > 400):
tax= (pourc_serv /100)* (SUP * 6.4 )
# Execute AddField
arcpy.AddField_management("Bati_Service","tax", "Double")
# Execute CalculateField
arcpy.CalculateField_management("Bati_Service","tax","tax", "PYTHON","")}

Here is the test code I was using inside ArcMap.  I've made a number of changes to your original code, including assuming the values for 'SUP' and 'pourc_serv' are in the 'Bati_Service' table; if not, the code will need to be adjusted on line 12.

This is what my 'Bati_Service' Table looked like, before:

and after:

If your table looks much different, add a photo showing some sample data.

If you get an error, please post it.  If the code works, then you can try pasting it into your button code.  The indentation should look similar to the example in my first posting.  Hope this helps.
