I would like to set up a membership fees page, which has a single fixed fee, and a separate donation page, where anyone can donate any amount of money. 

I currently have a members only section (not publicly viewable), where members of our non-profit can pay their annual dues, as well as a new members section (public) where new members can pay their annual dues after submitting their membership form. 

When I create a new donation page for general donations, the user is directed to the donations page with the fixed membership fee. This is despite me creating a whole new page which should have different donation amounts listed.

Can anyone advise me what I may be doing wrong?

Many thanks

Helen
