However, in my next step, I want to take the name of that selected layer and get a field value Stream_Name = arcpy.da.SearchCursor(lyrs, "GNIS_Name", "Any value", "")‍‍‍‍ I get the error  RuntimeError: 'in_table' is not a table or a featureclass Am I taking the wrong approach?  it seems to pass as a layer and not a feature class. ...

Just changing the data frame units does not change the units in the edit sketch window for me.  The only thing that will changes seems to be to set it to projection such as GCS_WGS_1984  that has angular units rather than linear units. Units in the sketch properties window and the guide that shows up in the lower left when editing seem to be controlled only by the coordinate system and not the data frame units ... View more

  The units default to meters, can they be changed to Decimal degrees? ... View more

And remember when you access your combobox you need to first have assign it properties through the class level self variables. You might be missing this part in your combobox class.     def onSelChange(self, selection):         self.sel = selection Then get the selection in your other classes like this. combobox.sel Awesome, I got it to work!  The whole code works great now, thanks for the help.  How about a bonus round? This is just a portion of the code, with this I populate the combobox with only unique values from the attributes, I want it sorted but something isn't working there, any ideas? Twp = [] for row in arcpy.SearchCursor("X:\JasonGraham\Landstatus\Data\ls2014.gdb\BaseData\Townships"):     Twp.append(row.TWP_NUMC) class ComboBoxClass5(object): #Collect Township from list of unique values gathered from the layer     """Implementation for MTR_addin.combobox_1 (ComboBox)"""     def __init__(self):         self.value = "000"         self.items = sorted(Twp)         self.editable = True         self.enabled = True         self.dropdownWidth = 'WWWW'         self.width = 'WWWW'     def onSelChange(self, selection):         self.sel = selection           #global valName         #val = (self.items, selection)[1]         #valName = str(val)     def onEditChange(self, text):         pass     def onFocus(self, focused):#show only unique values         if focused:             values = sorted(Twp)             uniqueValues = set(values)             self.items = []             for uniqueValue in uniqueValues:                 self.items.append(uniqueValue)     def onEnter(self):         pass     def refresh(self):         pass ...

print combobox? Are you trying to run this in an IDE? That won't work for addins. You'll only be able to reference the class values via the ID when it is installed as an addin. What is your end goal for this addin? ok, here is the whole code.  The original code works as a script but I decided to try making an addin tool. I am not a great coder, trying to learn.  This tool references a township and range layer, with the comboboxs the user can select meridain, township, north/south, range, east/west.  much of the code works to populate the pull down from the attributes with unique values but doesnt seem to sort.  I am able to pass the values for my Twp and Rng but not the M, NS, EW that have a list of values, I could populate like the other two but it seems to bog down,  suggestions?( no longer a simple question i guess)  alot of stuff on the bottom blocked out that I am working on. #

Then you probably changed it manually. Check in the addin assistant what the ID is for your combo box class.

You need to use the ID from the addin assistant. In your case it is called 'combobox' Nope, says combobox not defined.  Do you know of any better resources for arcpy addin, the python is different from scrpting ... View more
