Hm, could you talk more about your expected workflow?  A formula field with `{Q1}{Q2}` would get you the result you want, but it seems you want to activate this or something?

Here's an example but in Jotform:

I'd like to be able to do this in an Airtable form or interface is possible.

Ah, yeah I think that's not possible I'm afraid.  You could get functionality that's close to that in an interface with a record that already exists, but not for creating new records I'm afraid:

You could look into third party options like FillOut, On2Air etc for this though, I believe they have this functionality

This is exactly what I need - it was the Record Summary layout I needed. 

I looked at this before but didn't notice the Permissions setting in the right sidebar - I changed that to editable, and  can now calculate a field based on drop-downs, thanks for the help!

Hi @Owen_Smith , could you please explain how you managed to add a calculated field in a form?

I used an interface to achieve this, rather than a form @Rafael_Oliveira 

@Owen_Smith 
Could you please show me where? I am stuck trying to find a way to put a calculated field in a form, even in interface form, but I cannot find a way.
