Button click event from a noob

[jsampson]

I have a new outlook form I have created. When a button is clicked I want it to check a checkbox that is on the same form. i want it to do several things but this is good for now. Currently it does not even seem as though the button is aware of itself because if i type this.btncomplete.caption = "true" I get the error that the object "This" is required.
