Formula to add items to multienum

[tanya]

Yes, you are right. For this you need to use 'list' function

It appears that I need to use the list function. That isn't shown in the 'Function' menu in the gui.

I can't figure out how to set the values in a multi-enum using a formula. Nothing I've tried works. The entity saves without any errors, but the multi-enum doesn't have anything selected.

ifThen(
    entity\isNew(),
    ifThen(
        type == 'Z',
        timesheettasks = 'CAD'
    )
);

I've tried

timesheettasks = ['CAD']

and all kinds of other things, but nothing works. I want to add multiple values, e.g.

['CAD','Photos']

What do I need to do to accomplish that? Thanks.
