I have a Gallery that has worked assigned label, however I have a SP list that allows multi user selection. I have tried editing the lable to use the follwoing:
Concat(ThisItem.'Assigned To',value,",") which would work normally, however I also have a dropdwon and search function on my gallery, using this:
If(!IsBlank(WTRFTOOLSEARCH.Text),Filter('WTRF Database',Find(WTRFTOOLSEARCH.Text,'Tool Number'.Value)),Filter('WTRF Database','Assigned To'.Value=WTRFASSIGNEDDROPDOWN.Selected.Value))
The dropdown is to filter by the Assigned to Property however since i changed it to multi it has broken. Assuming because of the concat function.

All other labels have this error which i assume is linked to the Concat.

My general requirement is to allow multi users to be assigned the same job and log hours against it, and this WIP list needs filtering to individuals to allow them to see the work required. So on an itme with 3 people assigned I want it to show on all three of the peoples WIP list.
