Trying to get sidebar on sign up form page?

I am trying to add a sidebar to the signup page for one of my plans. I tried making a menu item using External URL, then copied and pasted the URL of the signup page but for some reason, when i apply the sidebar module to that page, it doesnt appear. Then I realized that if the signup page could be placed as a module, I could do it that way, but apparently there is no module for the signup pages. I dont use the PLAN pages, I just want to link directly to the SIGNUP pages. Anyone have a workaround for this? How can i do such a simple thing? I have no idea how to get any other elements on the signup page, and it is just white and plain and doesnt look very good. Thank you in advance.

I figured it out. Not that difficult. I see now that i can make a menu item directly to a subscription page. Never mind!

Great .
