plese talk slow lol thanks all

Hi slowdigits2,
when you modified the program to change the width you changed the J values.
you only needed to change the Y values. I would get in the habit of using decimals
because some controls would interpret 1 as .0001

thanks for your help mcode so i did as you instructed went a little futher then i noted i had not changed one of the ys thanks for your help i have a few more ?s well probbaly alot lol but the path is running fine thanks again for your help:banana:
