My daughters email account comes up on my iphone how do i delete?

When i go to download apps on my iphone my daughters email comes up and before i'm allowed to purchase app, it requires her password… It should be my email address and my password that should come up… Please help?

You will have to go on itunes and make a new account if you don't have one already and then on the app store on your iphone you will have to know the password and log out and then sign into yours i suggest you ask your daughter for her password
