Hello Terry,
Thank you so much for your feedback !
I just found the individual charges, the figures are:
proper charge ¥48,330, charged to sandbox ¥483,300, so proper cost x 10.
It should work fine in Euro, USD,... as they want the sum to be sent in the smallest unit ($1 = 100 cent). But it must be different in Yen.
Can you download the last Square version, install it and test it again ?
Also is there a way to turn off the postal code requirement?
You can try it by editing the file "square_end.php", but I actually tried it and it led to errors in my end, that's why we removed the "Disable post code" option.
Kind regards,
Mohamed Thelji.
