So I've set up fmserver with webdirect, uploaded my solution to the server all fine by now.
Create new record - done
When I try to add a line in a portal I get the Missing join value for creating related record. ERROR.
Tables are setup like this.
data_input - PKClientID
Actions - FKClientID
And from what I understand it seams to be a problem with the table relationship or something to do with how WebD handles portals.
