Visible income/expense front end/back end permissions

Perfect, I'll try it out. Thank you.

Didn't work, made it worse actually. See attached screenshot.

I think I figured it out because i had two groups and people weren't selecting the right groups. I chose one and edited the others to all be the same.

Does groups affect anything other than individuals?

Group is used to group Income/expense data of all the users belonging to a particular group.
