I have recently created a form only for my practice. I used MAILTO to send the form data through email. When I click the submit button, Firefox tells me to choose an application between GMAIL and YAHOO. I have chosen GMAIL and it took me to my GMAIL account to send the form. But in the body, something appearing like this:
Code:
name_f=Ahmed&name_l=Sadman&occupation=Student&email=waseerock99%40gmail.com&tel=&subject=Feedback
But my code was never supposed to do this kind of odd things. See the form code below:

Code:
<form id="contactme" method="post" action="mailto: muhib96@gmx.com?Subject=960GridSystem">
<fieldset>
	<legend>Personal Information</legend>
	<div> 
		<label for="name_f">First Name</label>
		<input type="text" name="name_f" id="name_f">

	<div>
