How to integrate data coming from 2 external forms into a single table

Hello @WanakaShow,
You need to use and read about how to use Airtable Automation. Getting started with automation in Airtable
It's the same as Zapier or Make if you've already used it for different API and tool integration.

Steps you need to follow.
- Create a summary table that includes relevant fields from both tables.
- What's important here is you need to track the trigger for rows when it's added to your "Declarations" and "Inductions" tables.
- Airtable Automation can read all the details about that specific row(which is added) and then on the next step(action) select the summary table fields that are relevant and come from the tables.

Note: you need to create 2 different automation to handle both of the tables.  Both tables have different fields.

Because you've used Jotform that's why I recommend you also check this new form builder called Fillout. They have inbuilt integration with Powerful forms for Airtable.
Fillout can be used for Scheduling, Automation, PDF Fill forms and Payments.

I hope this helps. 👍

As dilipborad mentioned, it's automation time! 

That said, I don't know if you necessarily need to create a summary table, but you do need a contact table that acts as the link between your declarations and inductions. A lot of this is dependent on your base construction and stuff like your primary fields in tables, but you can do a lot of automated linking with the right setup. A few tips...

• I usually use email as the identifying field, as people are liable to not capitalize, abbreviate, or otherwise minorly tweak company or personal names.
• The Find Record automation will be critical to any build, basically you start with your trigger, then you say Find Records in Contact table where email=submitted email.
• If you have linked tables where the primary table field is free text, you can generate new records in that table in automations by adding text to that field.
• In these kinds of builds, I'll usually do conditional automations, so your trigger fires, you do a Find records action, and then if Find Record is populated (contact already exists) then you have a series of update actions, but if Find Record is not populated (new contact) you have a series of create record actions. 

All of this can be done no-code in automations, you just have to play around with it. It's a bunch of logic puzzles really.
