How to assign the value to contain all events if using mvfind() in multiselect ?

[Jouman]

Hi all,

I deal with a multi-value fields and try to provide a multiselect dropdown for users.
Therefore, I use mvfind() in the setting for Token value(prefix) / Token value(Suffix).
Token value(Prefix) = isnotnull(mvfind( HWid, "
Token value(Suffix) = "))

It works well if I input one HW ID or many HW ID.
However, I get trouble in inputing "all".

I want to provide users all events by default but I am unable to find a way to do this by using mvfind().
It is similar as wildchar (all any values) to mvfind().
Is there any suggestion on how to provide all events on mvfind() ?

Thank you so much!

Set the value multiselect value for "all" to be .* so it effectively becomes

isnotnull(mvfind(HWid,".*"))

which will then find any value in HWid
