I do not know why... but doing a simple query now works..... John, all of the following queries (now) work.
: ($Selected_Search="has Inventory") QUERY SELECTION([Bench_Protocols];[Bnchprot_LabInv_Link]Bench_Protocol_ID=[Bench_Protocols]Bench_Protocol_ID) : ($Selected_Search="has Attached Files") QUERY SELECTION([Bench_Protocols];[BnchProt_File_Link]Bench_Protocol_ID=[Bench_Protocols]Bench_Protocol_ID) : ($Selected_Search="Is Used by an Experiment") QUERY SELECTION([Bench_Protocols];[Bnchprot_Exper_Link]Bench_Protocol_ID=[Bench_Protocols]Bench_Protocol_ID) The structure for all of these queries is: [Bench_Protocols] <--[BnchProt_xxxx_Link]--> [xxxx] I believe that it is possible to query across as many relations as you want/have as long as there is a (drawn line) relational path between the 2 tables in the query. ex: Query([Bench_Protocols]; [xxxx]Field=$SomeValue) On Wed, 24 Oct 2018 07:55:51 -1000, JOHN BAUGHMAN via 4D_Tech wrote: > Chip, > > I may be wrong but I don’t think you can query a table based on a > many table relation.
