missing code

[Vectisma1]

I am just learning EFS using the online video series http://www.esignal.com/support/esign...cript_efs.aspx and ran into a problem on the Functions section in the video the following code snippet generated the expected value

debugClear();

x = getMostRecentTrade();

debugPrintln(x);

When I did it I got this error message
C:/Users/Vectisma/Documents/Interactive Data/Formulas/Training/ex15_functions.efs, line 3: Error: Failed to call function 'getMostRecentTrade': not appropriate context 'global'.

That means that the function is used outside of a function. In this case the "main" function.
Just call the "getMostRecentTrade()" function from within main as in:

debugClear();
function main(){
    x = getMostRecentTrade();
    debugPrintln(x);
} 

If you want a value returned then the script must be loaded on a chart so it can retrieve data.
NOTE: a knowledgebase search for "getMostRecentTrade" will also explain that it can only be used in realtime.

A knowledgebase search for "variable scope" should also prove useful.
