display 'next-in-series' ID on Form

[Ambers]

When using a form to create a new entry the user needs to know what the ID for the record getting created is (so physical materials can be labeled with the ID and stored). 

IDs are sequential numbers and are unique.

Values are not created using the autonumber datatype.

ID should autofill and the user should not be able to change the value.

I think something like Max+1 should work but I can’t figure out how to make it work. Full disclosure, I am NOT a programmer which is why we are using Caspio (Although I am able to copy and past code if someone tells me what needs to go where..=-)

Does this need to be a dropdown? You can use Calculated value form element maybe?

(Select MAX(IDFIELD) FROM TABLENAME) + 1

It worked! I was struggling to get the correct syntax for a calculated value. Huge Thanks!
