Pict slider not lining up

Hi, Im creating a picture slider using PNG images. My BG only has 1 pic, my slider has 127. I can't get the slider image to properly slide through, for some reason it always goes through twice. attached are the pngs and below is the patch. Thanks! Edit - the slider png won't attach. It's horizontal, 127 images. Everything's correct with it as far as I see.

Edit: If anyone runs into this in the future, knobman makes a "stitched PNG" which is one file with all frames of the animation of the knob one after the other. the Pictslider object only needs a single image and it takes care of the "animation"/movement of the image itself.
