Count Multi-user Field & Remove specific users

[Denver Thomas]

____Counting

I have a multi-user field I need to the "length" of (the number of users)- field name "multiuser".

I've tried multiuser.asLength, asCount, AsSize, asArray.asLength, [entry.multiuser.asLength], [entry.multiuser.asArray.asLength, asArrayMultiUserPicker.asLength, etc etc.

____Removing

I also want an action button that allows users to freely remove themselves from the multiuser field.

I've tried the following according to: Virtual functions - Vertuna WIKI - ConfiForms

multiuser=[entry.multiuser].remove(dthomas)

multiuser=[entry.multiuser.remove(dthomas)]

Hi @Denver Thomas 

Simple example, hope it helps

Form configuration and the CardView as an example

Config for action button with action to perform set to

multiuser=[entry.multiuser.remove([entry._user]).asList]

Configuration to get number of multi-users in a field

Complete configuration

Perfect. I could have sworn I'd tried multiuser.asCount, but perhaps not . . . 

Thank you, Alex!
