I have some custom order_total modules, where by I need to display the totals to the customers in this way:

total (ex vat)
shipping
tax
grand total

Paypal would only display the total+shipping it would not add on the tax.

The only way I could get it to work was to set : $order->info['total'] = $newTotal;

newtotal included the tax on top. this works for both WPP and DP payments pro. Is this the proper way, is it safe to do this? is there another way?

Also in the customers->Paypal IPN page when someone goes through the normal checkout with either direct payments (paypal pro) or paypal express transaction type field is not filled in, and the price is 0.00 on express checkout.

Checking out with Express payments direct to paypal with its button when viewing the cart, every field in this table is ok. Is this normal behaviour?

Thanks
