So, after carefully following the steps and wiring in Sebastians video i've hit a dead end: I can't see the numbers?
I wanted it just like your video here:
(see picture 1 in the comment post)
I wanted to make it so i can just add in a segment inside the chip and it displays the current value of the chip.
Is this possible?
(picture 2 + 3)

The 7-segment display should show up at the green ones. (picture 2 above is how the 4-bit to 7-segment chip looks)
Also please re-add the negate sign again :)

In the save menu click 'customize', and then you can set how you want the displays to be shown
