How to cut path

[default7ahp8218hint]

Hello! I've been trying to figure this out for hours; I want to cut this light purple path so that that it lines up flush with the darker purple box. I've posted an image of what it looks like currently and what I want it to look like. I want to know how to cut the path rather than covering it up with white rectangle to hide like I did in the second image. Thanks!

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.

If cutting is neessary, you first deen to outline the path.
