ok what should i do now? i see it says
This transaction has been completed, but the total of items in the cart did not match the total of all items. 
For this i dunno what is wrong why would it not match.
and also
This transaction cannot be processed due to an invalid merchant configuration. 
i have tested with the sandbox aco**** for testing and also the real one none have worked so far yet dunno what else to change or do.
