problem creating grease groove between features

[gargoyle27]

i know i have done this before, but for some reason it doesn't want to work, i need to create a grease groove that only goes between the grooves on the edge (as opposed to the entire length) but i keep getting some kind of error (i am using a sketch on the end of the cylinder and extruding with the to-from command)

 

i was going to attach the file but it wouldn't let me, do i have to zip files first? i don't have winzip

What does the error say? if your sketch is on the end of your shaft you only need to use the To end condition and select the end of your shaft. Does it work if you use the Blind condition?

the goove is going between 2 other grooves, so its not touching either end of the shaft

 

the error says something about the end points i picked don't completely terminate the feature or something

 

i'm certain i used the same procedure i am trying now before and it worked just fine, so i'm lost

i just plain filled in the extra areas, doesnt look as clean but itll work, ive spent too much time on this already, thanks anyway

i figured out what it was if anyone wanted to know, the grooves were a different depth
