Hi, I really do not know what to do? I have tried everything but nothing works. The problem is that I have many items to include in the customer's purchases so it is a loop. for( $i=1; $i<=$maxpdts; $i++){ ?> <input type="hidden" name="item_name_<?php echo $i;?>" value="<?php echo $paypalarray[$i][0];?>"> <input type="hidden" name="item_number_<?php echo $i;?>" value="<?php echo $paypalarray[$i][4] ;?>"> <input type="hidden" name="quantity_<?php echo $i;?>" value="<?php echo $paypalarray[$i][1];?>"> <input type="hidden" name="amount_<?php echo $i;?>" value="<?php echo $paypalarray[$i][2];?>"> <input type="hidden" name="mc_gross_<?php echo $i;?>" value="<?php echo $paypalarray[$i][3];?>"> <?php } Unfortunately, both is sandbox and in 'live' performance paypal doesn't like more than 4 items in one transaction. I tried 8 items but it kept giving me "Things don’t appear to be working at the moment" when the customer tries to log into his account. I noticed that if there are 5 items it may give me a blank screen, but with 4 or less items I can do the sale. Is this a paypal bug? How do I fix this as I have about 30 items for customers to select. I checked the ID tokens and there are so many to use. There are merchant ID tokens, PDT tokens and many 'secrets'. Which do I use? Any help will be gratefully accepted. Best Regards, Peter
