A Movie in a Window Problem

Question

Hi All,
I have runned into another problem with my project that i
wonder if anyone can help me out. I have a movie in a window that
opens in my main project with a simple text-phrase (e.g., say
something). I want when the user clicks on this text phrase to
activate a spcified lingo script into my main movie. I have set up
the whole thing as follows
on prepareMovie
global gDemo
set gDemo to movie ("Greek-English_Non-AIML_Scenario.dir")
---Greek-English-Non-AIML_scenario is my main movie in which
the movie in a window opens
The script of the text-phrase is
on mouseUp
global gDemo
tell gDemo to switchToA
---switchToA is the script that i want to activate in my main
movie
end
I get the following error
"Script error can not perform tell void "
Any idea what is going on?
Many thanks for all your valuable help so far

It appears that sending messages from the main movie to the
MIAW works fine, but i can not figure out the vice verca.
Any ideas will be welcomed
Please help
Thanks
