Zoho Creator page take data from form

Zoho Creator page take data from form

Hello.

I am using Zoho Creator, but not Zoho Invoice.  However, some related functions are being done through Creator.

I created a page using the "invoice template" from in the pages settings / templates.

How do I draw the data from one specific form to populate that invoice?  I've changed the variables correspondingly, but I don't know how to invoke the data from one particular entry from a form.
