Form (button) Macro not working

Once again, I will call on the experts to help.
I have tried over the weekend to figure out what I did that renders the Form inoperable, but I am not that well versed in Macros as I would like to be.
I am creating a schedule for maintenence for equipment.
I would like to have the information required to be satisfied on the "PartsData" sheet available for input on the form (Parts Data Entry sheet).
It worked OK until I added the "comment" to the form.

The button on the form that adds the information to the last row on "PartsData"-sheet should also place the "part" in the calendar (2012) by matching the row (date) and column (issue) with the "code" in column F and H. So: once any equipment is schedulled for next inspection date, the click of the button places the equipment in the correct cell, referencing the row (date) and the column (issue).

Thank You for any insight and help you may give me.
