  syntax error??

  Posted by Mark Saliba on August 17, 2009 at 11:21 am

  Hi i’m kind of new to this whole expressions thing. So i obtained a code to use as a counter. Meaning like to count from 1 to 25 for example.

  Well this is what i did. I had the text layer and selected the source text and added an expression from the animation menu. But when i inserted the code and modified the numbers and tried to run it i got an error. It said there’s a missing bracket “)” in line 6.

  This is the code:

  var targetValue = 32; // final desired value
  var startShift = 25; // frames to skip before starting
  var display = 0; // starting value to display

  var internalTime = timeToFrames(t = time + thisComp.displayStartTime, fps = 1.0 / thisComp.frameDuration, isDuration = false);
  if (internalTime – startShift > targetValue) {
  display = targetValue;
  } else if (internalTime – startShift < 0) {
  display = 0;
  } else {
  display = internalTime – startShift;
  }
  display;

  Please help me sort out the problem and sorry for my ignorance in expressions.

  I created a new comp with 1000 frames using CS3 and CS4.
  Created a text layer.
  Selected the text, and added
  Animations Preset/Text/Expressions/Frame Number.
  Opended in the timeline the text and selected:
  Text/Source Text and held the alt-key and clicked the stopwatch to get the expression line. Replaced the existing code with yours.

  Ram tested the code…
  From frame 0 to 25 the display showed 0, then at 26, 1 was displayed all the way to 32. Then the remainder of the frame still only displayed 32.

  I could chaged vartargetValue=32; to 0 or 1000. all numerals worked including -1.

  I cannot get a syntax error. What version do you have?

  I don’t get a syntax error. Is the code you pasted that code that’s generating the error, or have you modified it in some way?
