In VB im trying to create a form. I have a few questions....

1) How do I assign the control box to a cell for the data to be populated in
the worksheet.
2) In combobox, how do I assign the input control to a range in another
worksheet so it contains the selections to pick from.
3) This has happened to me twice. I enter a word for the name of a control
button, such as OK or Type. VB gives me an error message of invalid name,
and then freezes with eh dialog box open. I can not click on ok or cancel.
I have to shut down excel and I loose all my changes?????

thanks.... tim

PS, is there is a good help/examples link that would help with forms... that
would be great!!!!!
