activex command buttons and text boxes

[TRG]

I am wanting to code a command button to clear the contents (reset) a group of text boxes, and check boxes in a MS Word 2007 user form (one button to clear the text boxes and one button to clear the text boxes and user boxes). I would also like to be able to set a tab index on those controls so a user can scroll though them. I'm able to do this in a VB form (clear the text boxes, and set tab index), but the same code for the command button doesn't work in word, and I don't see a tab index in the properties window for the activex controls. Any suggestions? Thanks
