I have a form "workorder" that I want to be accessed two ways. One, open a new form with a button on the "customer" form. Two, through another form "estimate". The difficulty I'm having is that when opening from the estimate form I want the data from it to populate the workorder using the estimate number to link, but if an estimate has not been filled out first, the estimate number would be null and the form blank to allow data entry. Should I have two different on click events for the buttons, or should it be looking if the estimate form is open in its on open event? Hope this makes sense.
