   From a quick look I see:
   inputtype='text'
   which needs a space like:
   input type='text'

   ==========================================================
   path : /wp-content/plugins/myplugin/options.php

   1. <form method='post' action='options.php'>

   result = Object not found!

   or

   2. <form method='post' action='wp-content/plugins/myplugin/options.php'>

   result = Fatal error: Call to undefined function add_filter() in D:\xampp\htdocs\thwordpress\wp-content\plugins\myplugin\options.php on line 23
