I see that one can set field values in scripts, but how does one set the value of a container field?

In particular, I have two fields ("IsRecordLocked" and "Signature"), the first is a text field and the second is a global container with a jpg of my handwritten signature. How do I get Signature to display my signature when IsRecordLocked = 1?

Thanks ahead for help.

Case ( IsRecordLocked = 1; Signature )

or, if IsRecordLocked is really text,

Case ( IsRecordLocked = "Yes"; Signature )

Calculation result is Container (important).

Signature is a global, hence available from anywhere without a relationship. But you would have to be somewhere where IsRecordLocked is available, as it's a regular field. Why is it Text? I would think Number? I don't use "Yes" myself; I prefer a Boolean number.

That worked wonderfully! And it was so simple. It's almost fun being a noob (which is my only rationale for using text over boolean, but I changed it per your advice). Thanks.
