I'm trying to create a set of webpages that work together to allow users to view, delete, and edit rows of a MS Access database using PHP.
Membership.php shows a list of the names of members in the Access database. Their names are also hyperlinks that, when clicked, take users to another page EditRecord.php where all of information on the member whose name was clicked on Membership.php is displayed in text boxes with the option to completely delete the record, or just update certain fields.
Membership.php and EditRecord.php are displayed below. The error code is for line 91 of my source for EditRecord.php, but I cut some things out of this post for privacy. Instead, the line has been marked like so:
//--------This is the error line----------

I also find this strange, because there are five records in my database, not four. Is that because it starts counting at zero?
Any insight or advice would be greatly appreciated.
