Hi darynbrown,

Please clarify if it is multiplexer or multiplier. It is multiplexer in your original post but it is multiplier in the circuit filename in your follow-up post.

I don't have Multisim (Desktop) application, I am only a Multisim Live (Free Subscription) user so I can't open the circuit file that you have attached.

Users who do not have Multisim (Desktop) might be able to help you if you can post an image (PNG format preferable) of your circuit schematic diagram.

Best regards,

G. Goodwin
