Why is Python AddIn toolbar showing all “Missing” tools/buttons?

Question

I am horribly new to coding with python. I made a toolbar using the wizard and old bits of VBA code. I created a button to search by map number, a tool to calculate area from UI and a second tool that would clear the area selected.

I get the following icons when I install the add in to test.

The following is what I have for my code:

import arcpy
import sys
import os
import pythonaddins

class ZoomToMapNumber(object):
    """Implementation for Test Addin_addin.button (Button) Everything from Import to del mxd is external code / deleted pass after 2nd def"""
    def __init__(self):
        self.enabled = True
        self.checked = False
    def onClick(self):
        mapno = sys.argv[1]
        mxd = arcpy.mapping.MapDocument("Current")
        lyr = arcpy.mapping.ListLayers(mxd,"SDEOWNER.MapIndex")[0]
        arcpy.SelectLayerByAttribute_management(lyr, "NEW_SELECTION", "\"MAPNO\" = " + str(mapno))
        result = int(arcpy.GetCount_management(lyr).getOutput(0))
        arcpy.AddMessage("Number of selected records: " + str(result))

        if result > 0
            df = arcpy.mapping.ListDataFrames(mxd)[0]
            df.zoomToSelectedFeatures()
            arcpy.SelectLayerByAttribute_management(lyr, "CLEAR_SELECTION")
            del df
        else:
            arcpy.AddError("No record selected for map number " + str(mapno))
        del lyr
        del mxd

class CalcDrainArea(object):
    """Implementation for Test Addin_addin.tool (Tool)"""
    def __init__(self):
        self.enabled = True
        self.shape = "Line" # Can set to "Line", "Circle" or "Rectangle" for interactive shape drawing and to activate the onLine/Polygon/Circle event sinks.
        inputs = []
    def onMouseDownMap(self, x, y, button, shift): # Inputs x,y coordinate pair to inputs for every mouse click
        for coordinate_pairs in (x, y):
            inputs.append(x, y)

    def onDblClick(self, x, y, button, shift): # Inputs the final x,y pair and the first x,y pair as last four values into the 'inputs' array
        final_x = inputs[0]
        final_y = inputs[1]
        inputs.append(x, y)
        inputs.appent(final_x, final_y)
        return inputs

    def calc_drainage_area(inputs) #takes (x1, y1, x2, y2, ... xn, yn)
        cArea = 0
        # Calculate the area based on the Surveyor's formula
        for i in range(0, len(x)-1):
            cArea = cArea + x[i]*y[i+1] - x[i+1]*y[i]
        cArea = abs(cArea / 2)

class ClearArea(object):
    """Implementation for Test Addin_addin.tool_1 (Tool)"""
    def __init__(self):
        self.enabled = True
        self.shape = "NONE" # Can set to "Line", "Circle" or "Rectangle" for interactive shape drawing and to activate the onLine/Polygon/Circle event sinks.
        mxd = arcpy.mapping.MapDocument("Current")
            for elm in arcpy.mapping.ListLayoutElements(mxd, "TEXT_ELEMENT"):
                elm.delete()
            arcpy.RefreshActiveView()
            del mxd

The following is the xml that results

Answer 1

A broken record here but, having the Python window opening when adding in the toolbar to your map will often tell you where the problem is in your code.

But I think your problem might be with the spaces that you have in the name of your tools and buttons. Additionally there is a discrepancy between the name of your button in your Python code and the resulting XML. Your Python code is listing the name of the button as

"""Implementation for Test Addin_addin.button (Button) Everything from Import to del mxd is external code / deleted pass after 2nd def"""

but the xml has it as

id="Drainage Test Addin 2_addin.button" 

So 1) I think these should be the same if you haven't altered the name in the Python code itself. 2.) Try naming the tools and buttons without spaces in the Addin Wizard. For example "Drainage_Test_Addin".

Since you are new to coding I would suggest taking the functioning VBA code you have and try implementing a single button or tool on the toolbar. Once you get the hang of that you can add more buttons. This will of course require you to start over from scratch with the Addin Wizard as others have suggested.
