Yep, here you go:

What I did was, first, replace the Real user data with Integer user data. The second digit data goes from 0-10. I set it up that way because the second digit drives the first digit.

To that end, I added a second range mapper to drive the digit 1 slider with the digit 2 slider. If you turn on the range mapper's modulo function, what happens is that the output resets to the lower value when the upper value is exceeded, and the sequence keeps repeating. So the range mapper's input goes from 0-99 and the output goes from 0-10.

Accordingly, as long as the second digit's input ranges from 0 to 9, the first digit remains at 0. When the input hits 10, the second digit flips to 1 (because the slider 2 range mapper is set to 0-10), and the first digit flips from 9 back to 0, because that's the 11th value on the slider and it trips the modulo function.
