Counter + Blinky expression
I have Dan’s standard counting expression.
Would it be possible to affect opacity once it reaches a certain number?
Here’s the non-code version: Count from 000 to 250 over 2 seconds starting at the layer in-point. Once the value equals 250, blink the opacity off and on three times (3 cycles of 2 frames on, 2 frames off) and then remain at 100% opacity

I don’t think this is optimum, but something like this modified source text expression might work:
numDecimals = 2;
commas = true;
dollarSign = true;
beginCount = -1999;
endCount = 1999;
dur = 4;t = time - inPoint;
s = linear (t, 0, dur, beginCount, endCount).toFixed(numDecimals);
f = timeToFrames(t-dur);
if ((t > dur) && (f < 12) && (f%4 < 2)){
"";
}else{
prefix = "";
if (s[0] == "-"){
prefix = "-";
s = s.substr(1);
}
if(dollarSign) prefix += "$";if (commas){
decimals = "";
if (numDecimals > 0){
decimals = s.substr(-(numDecimals + 1));
s = s.substr(0,s.length - (numDecimals + 1));
}
outStr = s.substr(-s.length, (s.length-1)%3 +1);
for (i = Math.floor((s.length-1)/3); i > 0; i--){
outStr += "," + s.substr(-i*3,3);
}
prefix + outStr + decimals;
}else{
prefix + s;
}
}
If it really needs to be opacity, you’ll need to synchronize the two expression.

That works great! Thank you!
How would you keep leading/trailing zeros? (need 5 is displayed as 005.0)
And what line controls the duration of blinks/number of blinks?
