Fieldstack Walk

["Michal Kvasnička" <quasar@econ.muni.cz>]

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
