Hi, Recently tried to integrate paypal express mobile payments into our small store. It works if you click through the link on a computer, but if you try to go through a mobile browser (safari on my iphone) it doesn't - but it does take you through the whole payment process, and send you through to the 'success' page. I asked paypal what was wrong and they said... "I do not see the GetExpressCheckout and DoExpressCheckout beeing called by your Cart once the buyer gets redirected back to that URL. Please check the PHP script files and review the integration locally. DoEC must be called by your Cart to initiate the actual Payment and so transfer of money." But I am now out of my depth. Can anyone help?
