Default easing options not working when using easing plug-in

Default easing options not working when using easing plug-in

When I use an easing plug-in, the default easing options "linear" and "swing" are no longer available.. when I try to use them, I get a javascript error from my jQuery file (jquery-1.5.2.min.js) saying " d.easing[j || k] is not a function". I've tried two different easing scripts ( here and here), but same result with both. This is an issue as I would like some way to do a linear movement.

This behavior happens in jQuery 1.5.2 as well as 1.5.1 and 1.4.4 and is an issue in all browsers I've tested in: FF (mac/pc), safari (mac), IE (pc), etc. Has anybody run into this before?

Some example code:

  1.        $(obj)
  2. .css(
  3. {
  4. "left": -971
  5. }
  6. )
  7. .animate(
  8. {
  9. "left": 65 
  10. },
  11. {
  12. "duration": 800,
  13. "easing": "linear"
  14. }
  15. );
