Is it possible to place X on my form that will act as closing button?

2. Can I put an X on the top right of the form to close the window?

You can try inserting the below HTML in your form's code:

<input type="button" value="Close this window" onDISABLEDclick="self.close()">

If that doesn't work, please try with this JavaScript code:

Step One: Insert the following lines of code into the head of your HTML page.

<script language="javascript" type="text/javascript"> 

function windowClose() { 

window.open('','_parent',''); 

window.close();

} 

</script>

Step Two: Insert the following line of code into the body of your HTML page.

<input type="button" value="Close this window" onDISABLEDclick="windowClose();">

You will have to copy that code in code of your website.
