parametric relation of the same length (problem)

[NANODESIGNER]

Hello, I desperately need help. I do not have problems with solidworks, I use it quite well, but I can not make this passage of a tutorial to this link_video of youtube. the video sequence goes from min 1:12 to min 1:50. I can do the steps from 1:12 to 1:46 but I can't finish, when I go to press on the icon to make "length curve equal" (symbol

), this passage does not happen and does not complete, I follow all the passages of the video but in that passage fails. I uploaded the video sequence (link) while trying to make the steps, I put here the link to show you the comparison with the youtube tutorial. I really need help. Thank you in advance.

found the magna...after you create the spline you have to remove the relationship optimizes.
