If your error is on line 490, one of two things is likely happening.

  1. Your FILEHANDLE for phonenos did not open.

    You could be attempting to access the file from a bad location, it may not exist, or it could be write protected.

  2. Your contact array is referencing an invalid index item.

    Is counter going outside the range of the array? Is this a zero (0) or one (1) based array?
