  Why doesn’t this simple expression work?

  Posted by Randy Mcwilson on January 18, 2009 at 4:43 am

  I am trying to increment a position by using the following:

  x=value[0]
  if (some situation){
  a=1
  }
  {else
  a=-1}
  x=x+a
  [x,100,200]

  this only makes my x value change to, lets say, 99 or 101. Why doesnt it make it continually change lower and lower, or higher and higher? I only get 2 possible x positions.

  strange.

  Definitely one for the FAQ: this question has been answered numerous times,
  Check the thread “movement with expression” from last week for the most recent one.
