  hi
  I know how to set my text to animate, but i cant figure out how to get a number value from 0 to 100? How do i use wiggle to get this done?

  You could “borrow” one of the other properties, like rotation, with a source text expression like this:

  w = 50 + (transform.rotation.wiggle(.1,50) – transform.rotation);
  w.toFixed(0)

  Ok sorry if I wasnt specific enough. first off all.i am new to expressions, so can you advice in simpel steps. Second I just want a text animation value with the number 0 going to 100 and then stops at 100.

  What is the easiest way for this?

  This expression will count from 0 to 100 over a 4-second interval.

  startT = 0;
  endT = 4;
  beginVal = 0;
  endVal = 100;
  t = linear(time,startT,endT,beginVal,endVal);
  t.toFixed(0)

  Steps:

  1. Copy the expression
  2. Alt+click the Source Text stopwatch
  3. Paste the expression

  thanks so much Dan. I will try this when i get home today. I think it is just what i need. So in 4 seconds it goes from 0 to 100 and stays there, am i right?
  One last question if you be so kind, how do i get a blinking effect. I mean e.g the word scanning should blink/apear and disapear. Like a robot scanning for an object. I hope you get the idea.

  There are many ways to do this. One would be to keyframe one on-off cycle of the layer’s opacity and add this expression to the opacity property:

  loopOut()

  ok. You mean that i keyframe an opacity value of 100 and then a couple frames later i keyframe to 0 and then add the script?
