That's all folks, thanks, Roy
Others have told you how to open the 2 forms.
If you then wish them to be set side by side use each form's Load
event to position the forms where you wish them:
Code the left side form's Load event:
DoCmd.MoveSize 0.5*1440,2*1440
Code the right side form's Load event:
DoCmd.MoveSize 5*1440,2*1440
The first form will be placed 1/2-inch from the left of the screen and
the right form will be 5 inches from the left edge of the screen. Both
will be 2 inches down from the top of the screen.
Adjust the values as needed.
Note that all measurements must be in Twips, 1440 per inch.
