Hi, Guys!
Can someone out there help with knowledge about form posting method.
I've got basically this code:

<form method="post" action="SubmitePurchases.asp" id=form1 name=form1>
<p><INPUT type="checkbox" id=checkbox1 name=checkbox1><INPUT id=text3
name=text3></p>
<INPUT TYPE="image" SRC="images/UpdateBasket.gif"  BORDER=0 align=absMiddle
name="Updatebasket" value="Updatebasket" alt="Update basket.">
<INPUT TYPE="image"  align=absMiddle src="images/Submit.GIF" alt="Submit the
purchases." WIDTH=70 HEIGHT=17 border=0 name="Submitpurchase"
value="Submitpurchase">
</form> 
I want to  know what image caused to get into  SubmitePurchases.asp.
I have then treat differently the controls from the form.

Thanks, Sergey.
