title: paypal express checkout -ordertotal invalid error
body: <p>Am using pay pal express checkout for a shopping cart site. My final amount is spliting into site admin fee and seller fee based on a site admin fee percentage.
  In my expresscheckout.php file
  if i choose site admin percentage as 10 then
  10% of total amount is given to site admin and remaining to seller</p>
  
  <p>$siteowner_amount   = (($paymentAmount)*$admin_percentage)/100;</p>
  
  <p>$seller_amount      = $paymentAmount-$siteowner_amount;</p>
  
  <p>$str                = "&amp;PAYMENTREQUEST_0_AMT=".$seller_amount;</p>
  
  <p>$str                = $str . "&amp;PAYMENTREQUEST_1_AMT=".$siteowner_amount; </p>
  
  <p>and also passing the total amount to my paypalfunction.php file
  Am getting the correct total amount in my paypalfunction.php (sum of siteadmin fee and seller fee). and also succeed in paypal sandbox.
  But my issue is that when ever am using the site admin percentage less than 10, and even though the total amount is correct , am getting the error </p>
  
  <p>"10401 order total inavlid Transaction refused because of an invalid argument. See additional error messages for details." </p>
  
  <p>But its works fine for admin percentage 10 and greater. only issue with less than 10 .
  i checked the sum total that i am getting in paypalfunction.php ,it is correct.</p>
  
  <p>Please help.
  thanks in advance</p>
