The "username" and "userid" are field name right? and type is "formula" ..But you can't put formula if you don't enter "expression"?
in the given example theres a two fields username and userid but their type is "formula" is it possible that you can convert a field to formula in free flow?
username
(
type = formula
value = zoho.loginuser
)
userid
(
type = formula
value = zoho.loginuserid
)
