I'm receiving an "#INVALID DATA TYPE" result with the following forumla:
=JOIN(COLLECT({LocationStrings}, {LocationStrings}, NOT(ISBLANK(@cell)), {PersonNames}, @cell = $[Person contact list]29, {ProjectStatus}, OR(@cell = $Status$5, @cell = $Status$6), {DeliveryDate}, AND(MONTH(@cell) = MONTH(TODAY()), YEAR(@cell) = YEAR(TODAY()))), ", ")
When I remove the last collection criteria, it works, however I need the extra criteria:
=JOIN(COLLECT({LocationStrings}, {LocationStrings}, NOT(ISBLANK(@cell)), {PersonNames}, @cell = $[Person contact list]29, {ProjectStatus}, OR(@cell = $Status$5, @cell = $Status$6), {DeliveryDate}), ", ")
