Number Counter Expression

Hey all,

I'm trying to animate a text layer to increase from 0 to 3,000,000 however I've run into a couple of issues. I quickly figured out that the slider control expression is capped to 1,000,000 so after reading over a few posts about how to get around this I've ended up with this code which has been applied to an empty text layer (keep in mind I am completely new to writing code like this and thus have copied this from another user's post with only a basic understanding of how it functions). My issue is that while this code works the way I want, it begins counting at the start of my timeline, instead of where I need it to begin, and if I physically drag the text layer to the point I need, the number freezes on 3000000 instead of counting upwards from zero when played back. Is there something I could add to this expression so that it starts at a specified point in my composition?

startCount = 0;

endCount = 3000000;

countDur = 14;

Math.round(linear(time,0,countDur,startCount,endCount))

Try this:

tStart = 3; // start 3 seconds into comp
startCount = 0;
endCount = 3000000;
countDur = 14;
t = Math.max(time-tStart,0);
Math.round(linear(t,0,countDur,startCount,endCount))

there is a different approach to solve this by Linking the Source Text value to a Slider/Point Control and animating them.
Counter Preset is based on that solution so you can create any Counter and running numbers animation, with keyframes. I hope you will find it useful. you can get it here:
