That did it! Thank you so much for all your help, everyone!

Hi Richard - I set these filters within a report, but it didn't allow users to bulk edit their tasks unless they were listed as the project owner. I haven't tried it on a layout dashboard yet, but wondering if the functionality would be different? 

I think it may be because it's on an Hour report, and not a Task report as I previously said (my mistake!). I'm working on a report someone else created, but if I can't get it to work on the hour report I may just create a new report as a better work around. Thanks again! 

No, unfortunately it didn't work. Thank you so much though for replying!
