Hi, after following your instruction, now it displays correctly in the checkout page. But I still have alignment problem in the cart page as you can see here https://www.dropbox.com/s/kdcpzpb5ry7ik10/SC23.png?dl=0. The plugin author said this is an alignment issue of css of the them. I also change to the default theme, there is no any problem as you can see here https://www.dropbox.com/s/obda8whlb4aho9x/sc24.png?dl=0. However, this alignment occur es when changing to Woodmart theme.
