Hey how do I customise the print template of an opportunity form? I can't see it under the Advanced PDF/HTML or Transaction form PDF or HTML options not sure where I am going wrong!

What is your use case in wanting to print this out? The opportunity is meant to be used as an internal record, it doesn't go to customers, so I can't see why this data will need printing out?

We are using opportunities for quoting our members on having their gas quotations with us for their gas sites and they can have multiple gas sites per opportunity so we have a custom record which is the child of the opportunity. We need to send emails out to suppliers containing all gas sites relating to this opportunity in order to obtain prices and email templates we have had no luck, advanced PDF templates we can't extract child record fields and the default print template does show the child records so was hoping we can customise it to make it look nicer
