the 'act' command

[Kevin]

ok thanks 
from my test function you can see that i could only get act child(F"{fileName}") to work by activating the parent window

str fileName=F"{chn} {cn} {pn}"
this doesn't work . is there a way to format fileName so it works in act child(F"{fileName}") ? 
could figure it out. had to do either
act child(F"{chn}" F"{cn}" F"{pn}")
or
fileName=F"{chn}"
act child(F"{fileName}" "SysTreeView32" "Quick Macros")
or
activate parent window 
fileName=F"{chn}"
act child(F"{fileName}")
then would work
