Hey Daniel,
Actually is a great question. You are right about this. The maximum number for the slider control is 1.000.000. We can’t go further than that. You can bypass that by editing your expression and multiply it by 98000, so you can reach 98.000.000.000.

I assume you control your count text through a null object with slider control.
Make the following animation: In frame 0, set the slider control to 0. Go as many frames as you need forward and set the slider control to maximum, which is 1.000.000. Then, go to your source text expression and click on it to edit it. At the end of your expression add *98000. This will multiply your slider control by 98000. So your expression will look like this:

thisComp.layer(“Null 1”).effect(“Slider Control”)(“Slider”)*98000

Lastly, don’t forget to add the Math.round function at the beginning of your expression and put the necessary parentheses. Finally, your expression will look like this:

Math.round(thisComp.layer(“Null 1”).effect(“Slider Control”)(“Slider”)*98000)

I am glad you find the post interesting Danny. I wasn’t aware of the Counter Preset tool, thank you for that. It looks like it could save a lot of time with great potentials.
