Keep getting parse error when I try to use Custom Field to add a member

Question

I am trying to set up a trello board to add a member to a card when the custom field is set.  The custom field is "Coach" and I am trying to set the coach as one of my co-workers which varies based on who gets assigned to it.

I tried using {{%Coach}} in a rule and just got the CANT PARSE ERROR.

Can anyone point me in the correct direction?

when custom field "Accountability Coach" is set by anyone, add member @{{%Accountability Coach}} to the card

@Bobby_Grant_Jr nope they'd need to be a member of the board. If you wanted to use username as a means of first adding a member to the board then adding them to all cards labelled with the name of the custom field this Trellinator function would do it, you can't invite members to boards with Butler anymore:

I tried it too and worked thank you. Maybe a dumb question but if I try adding a member who isn't already on the board to a card will it add that member to the board?

@Bobby_Grant_Jr okay well when I did a simple test of this the only time I got a parse error was when I had a space in the custom field name, with no space in the custom field name it worked as expected
