Hello, Greetings! of the day. I have checked attached image files, in which, reservation details section is displayed for backend and frontend of your wordpress website, using "homey" theme. As mentioned in project description, your requirement is to add a line showing "Balance due" field in the reservation details section on frontend as follows:
1) The value of meta field "reservation_balance" should be retrieved.
2) This value should be added in reservation details section on frontend, below "Deposit" line.
I have extensive experience in doing customizations in projects, using PHP, wordpress, different themes, wordpress hooks, filters, metadata management. Your work will be done, according to requirements, ensuring that the styling and layout remain consistent with the current design, following good practices for wordpress theme modifications.
Thanks.
