DB Read Just the primary key "id"

I need a bit of help. I am doing this because two people are going to manage this.
First thing is when a user clicks "submit" on the form I am doing a DB SAVE... that works just fine.

As part of the "Submit" process I am doing the paypal redirect for payment.

I am trying to do a DB READ from the record I just saved to pass that as part of my paypal item info... the reason for this is someone is getting the forms on submit, someone else is processing the payment. If I have them pass this primary key info back and forth (e.g. EVENT SUBMISSION - W15" <-the number 15 being the primary key).

So how do I:
[list]Read the latest record which was just entered into the database?[/list]
[list]Parse this ID into a variable, not array?[/list]

HI msreyes,

After the DB Save the new record ID and the saved data are added to the $form->data array - add a Debugger action temporarily to see exactly what is there.

So I do not need to do a DB READ after a DB SAVE?

HI msreyes,

No

Ok, I am struggling😟

Here is my database "Save"



After I do this I send an email, then do the paypal redirect. In the "Item name field" I am looking to also pass the "id" from my database save.

In my array I have (debug):

Array
(

[Data] => Array
(
[id] => 42
)

)

As silly as this sounds, how to I get just the number 42 into a variable I can use elsewhere?

Awesome! Thanks.
