BUTTON LINKS NOT WORKING CORRECTLY

I am using Version 10 - finding out it is not as good as Version 9 ...has problems that I never had in Version 9..

I am working on creating a website...I have been setting up the buttons to take you from one page to another and then back...
Links are all correct, checked and double checked them...
When I go into Website Preview to test them, some of them are not working.. it's as if I never linked them to the other page I need to go to...
I go in and delete the button and put in new button, do my link... now this button is working but another stops working...

Why would the button not work on the website preview but they all are correctly set up and when you check them in the program, the links are all correctly in place

thanks

Are you creating the buttons separately or creating a Navigation Bar?

If the buttons are indeed linked to the correct destinations, and are not working, select the button or buttons and bring then to the front (Arrange > Bring to Front).
