I have contacted the paypal guys. They said it's a setting issue. May I know what is the error in the above code? Please help me out for this issue please?

Answer 1

You must use in your html form parameters "p3" and "t3".
p3: Specify an integer value in the allowable range for the units of duration that you specify with t3.
t3: Regular subscription units of duration.
Allowable values are:D – for days; allowable range for p3 is 1 to 90W – for weeks; allowable range for p3 is 1 to 52M – for months; allowable range for p3 is 1 to 24Y – for years; allowable range for p3 is 1 to 5
Also the cmd parameter must be _xclick-subscriptions instead _cart
Follow this example:
<form method="post" name="formName" id="submitThisForm" action="https://www.paypal.com/cgi-bin/webscr" >
<input type="hidden" name="cmd" value="_xclick-subscriptions">
<input type="hidden" name="business" value="your#papypamail.com" />
<input type="hidden" name="item_name" value="Your Membership" />
<input type="hidden" name="a3" value="0.01">
<input type="hidden" name="p3" value="1">
<input type="hidden" name="t3" value="M">
<input type="hidden" name="src" value="1">
<input type="hidden" name="sra" value="1">
<input type="hidden" name="item_number" value="2" />
<input type="hidden" name="custom" value="SECURITYCODE" />
<input type="hidden" name="currency_code" value="USD" />
<input type="hidden" name="quantity" value="1" />
<input type="hidden" name="no_shipping" value="1" />
<input type="hidden" name="return" value="page going after payment" />
<input type="hidden" name="cancel_return" value="" />
<input type="hidden" name="cbt" value="ITEM DESCRIPTION" />
<input type="hidden" name="rm" value="2" />
<input type="hidden" name="notify_url" value="your_listener_file.php" />
The allowable range for parameter "p3" is 1 to 24.
In your case must set
<input type="hidden" name="p3" value="1">
AND
<input type="hidden" name="t3" value="M">

Answer 2

It is appear you are not created a subscription button because the value="_s-xclick" is missing. For subscription button you shopuld specified below variable in your button code ;
<input type="hidden" name="cmd" value="_s-xclick">
