Changing a few specific things throughout checkout

First of all, I have HikaShop Essentials and I LOVE IT. My customers are solely in America, so I have a few minor tweaks I need to make. On checkout, I have a box for Billing Information, but the fields are not in the order I'd like them to be. Right now it's:

First Name
Last name
Street
Post Code
City
Telephone
State
Country

I'd like to move Post Code and Telephone under the State and Country drop downs. I would also like to change "Post Code" to "Zip Code"

Lastly, I would like to change the value of the button at the bottom of the form to "Next" instead of "Register"

I am capable of making these changes, but when I went through the files in components/com_hikashop/views I didn't see any files that looked correct. Can someone tell me what file(s) I would need to edit to make these changes?

Thanks!

Hi,

You don't need to edit any files for that.

For the address, you can change the order of the fields via the menu Display->Custom fields.

For the register button, you can change it by overriding its translation, like any text in HikaShop:

Perfect! Thank you so much.
