[NTG-context] Fieldstack Walk

Good morning. I use a fieldstack in my presentation. I'd like to go to the next frame when I click on the figure. I tried this: \definefieldstack[fgolds3] [sgolds1,sgolds3a,sgolds3b,sgolds3c,sgolds3] [frame=off,clickin=JS(Walk_Field{fgolds3})] \definesymbol[sgolds1][{\externalfigure[golds1]}] \definesymbol[sgolds3a][{\externalfigure[golds3a]}] \definesymbol[sgolds3b][{\externalfigure[golds3b]}] \definesymbol[sgolds3c][{\externalfigure[golds3c]}] \definesymbol[sgolds3][{\externalfigure[golds3]}] \placefigure[here]{none}{\fieldstack[fgolds3]} I thought that `clickin=JS(Walk_Field{fgolds3})' makes precisely what I need, but it does not. How can I make it work? With many thanks yours Michal Kvasnicka
