Insert Comment If Checkbox Is Ticked

I am working on a database which will basically serve to be a massive Auditing Checklist. Lots of "Is this done" type yes/no questions to record, some with a comment.

Brief Description: I have many child-forms on a tab-control, each with a different heading/category of things to check for. When someone visits a store, I would like them to record their findings in this form.

In the above example, if the Floors are clean, no input is necessary. If the floors are not clean then the user ticks the checkbox and the text "Floors were not clean" should be automatically entered into the field: Cleanliness 1. The reason for this is that I wish to link the value from this field to a Microsoft Word document using mail merge for reporting purposes, and in the report it needs to state any problems in full sentences.

I have tried using this code in order to update the comment field when the checkbox is ticked, however, the problem with this is that I would have to insert code manually for every single checkbox in my forms, and I have about 150 checkboxes in total.

Code:
Private Sub Cleanliness_A1_AfterUpdate() If Cleanliness_A1.Value = -1 Then 'If checkbox is checked
Cleanliness_C1.Value = Cleanliness_C1.DefaultValue
Cleanliness_C1.Enabled = True
Else
Cleanliness_C1.Value = ""
Cleanliness_C1.Enabled = False
End If
End Sub
