Anybody know how to make it reset the counter back to zero at a number for say, 6, instead of going 0-1-2-3-4-5-6-7-8-9- (then starting back at zero)

I want to make i stop at 6, 0-1-2-3-4-5-6-0-1-2-3-4-5-6 and then carry the number, which is simple enough

But I don't know how to set it up so I can reset at 6? or so it knows to reset at 6?

I'm not familiar with Multisim so I do not know the correct syntax, but to achieve the reset, you will need to do modulo 7 on the counter variable. E.g. (counter MOD 7) will produce the 0, 1, 2, 3, 4, 5, 6, 0, 1, 2,.... pattern.
