in reply to next and previous buttons

You have this:

<!-- Next Photo Button Form --> "<button onclick="window.navigate'"; " +20122&more=Becky_and_Jason&name=Before_the_Ceremony&value="; ["+1"]; "&goback=&select='; "">Next</button> <!-- Next Photo Button Form --> + <!-- Back Button Form --> <form action="" method="POST"> <input type="hidden" name="class" value=Before_the_Ceremony> <input type="hidden" name="value" value=Before_the_Ceremony> <input type="hidden" name="place" value=1> <input type="hidden" name="student" value=C173B200.jpg> <input type="hidden" name="select" value=> <input type="hidden" name="id" value=20122> <input type="hidden" name="more" value=Becky_and_Jason> <input type="hidden" name="recipientnum" value="+1"> <input type="submit" value="BACK" name="back"> </form> <!-- Back Button Form -->

The top section is gibberish. You are trying to use javascript to call a Perl CGI but don't seem to have much of a clue about what is and is not valid HTML/javascript syntax.

The OUTPUT that is generated by the Perl CGI needs to change to be:

<button onclick="window.navigate(' +cgi-bin/ +re_the_Ceremony&goback=&select=&value=+1')">Next</button>

This needs to be generated in your Perl code. BUT it does not work as is because the CGI does not understand the concept of a value +1. It wants something C173B202.jpg as a value where this value is the name of the next picture to display.

You need to post some of the Perl code if you want more useful help. When your code displays an image it needs to get the name of the next image. This will be at index +1 if the names are in an array which is probably what your +1 represents. You then need to output HTML that looks like the example above with the +1 fixed.
