CCS: GEL files and global variables

Tool/software: Code Composer Studio

Hi there,

for my application I need to share variables between the C project and the GEL file, doing something like this:

C project:

short TestId=0;

while(1)
{
   if(TestId != 0)
 // Execute some code.. 
}

GEL file:

menuitem "Test"

hotmenu Test1()
{
  TestId=1;
}

I load the GEL file and launch the configuration, but when I select he "Test1" script I get this error: "identifier not found at TestId=1".

What am I doing wrong?

Thank you
Regards
