Cannot use path on word! value

Hi guys: I'm trying to change (by code) the state of several toggles every time the user clicks on a check box. This is my code and the error message I receive. Why? How can I do that? Thanks R E B O L [] view layout [ chkAll: check-line "All of them" [ foreach tg [tgA tgB tgC] [tg/state: chkAll/data show tg]] tgA: toggle "A" tgB: toggle "B" tgC: toggle "C" ] ** Script Error: Cannot use path on word! value ** Where: func [face value][foreach tg [tgA tgB tgC] [tg/state: chkAll/data show tg]] ** Near: tg/state: chkAll/data show tg

Ok, after digging anywhere I took an idea from vid-build.r, here is the solution: R E B O L [] view w: layout [ ; use w to get every face in the layout ; next, use face instead of tg so i can reach the state refinement ; of course, not all faces are toggles so check it out first -chkAll: check-line "All of them" [foreach face w/pane [if face/style = 'toggle [face/state: chkAll/data show face]]] -tgA: toggle "A" -tgB: toggle "B" -tgC: toggle "C" ] Now it works fine
