Hello
I have over 28 years extensive experience with Filemaker Pro (almost as far back as when you first used the original FileMaker as well) and have developed, deployed and maintained many instances from very large and complex down through to small more simple deployments.
I can help you to build the export script that you are looking for, I did have a look at your project details and attached image and it is doable.
If you would like to contact me with some further details, including which version of FMP you are currently running and also what system you are looking to upload to for your webstore(s), we can discuss further and confirm from there.
Thank you
Darren
Edit: After looking at your attached image again, it appears you want to search for a PROD_CODE and a DESIGN_CODE that are not currently related through any primary/foreign key (ie. the FLWR records do not contain the KRING PROD_CODE field), is that correct? Either way it is still doable to create a one-to-many output relationship and export the combined data details as a csv file.
