Your duplicate thread was deleted – you need to include more information for anyone here to help you.
Link to your site?
What theme?
What form plugin, if any?
http://embracesbywendy.com/ my website
http://wordpress.org/plugins/custom-contact-forms/ The plug in I’m attempting to use
and Marriage theme I believe
I want to change the form that’s there to the customixed one
thank You
For help with a plugin, you can post on the plugin’s support forum:

But I suspect you need to ask the theme developer how to remove the existing form/page first.
