I can't find the string to my last question...so here goes

Hello,

I can't find the string to my last question...so here goes as part remains unanswered.

Protected Content seems to pull from a php file to set/style the initial page...would that be page.php? Does it work off of page.php or another file? When I make changes to page.php it seems to affect the membership pages...just want to make sure that I am not missing anything

Also, is there any way for me to control/edit what is in [ms-membership-signup]? I only need the sign up button and don't know how to remove the remainder. The page explains the price, membership name, etc.
Also for some reason in Safari the [ms-membership-signup] portion outputs the copy "Add Membership Level" but NOT in Chrome (see attached PDF). I just want to remove all the copy other than the sign up botton associated with [ms-membership-signup]

Thanks!
