    Well, of course you get an error, since inside the abcfunction1 function you declare a new one (local) variable, which is destroyed after the function exits.



    But this question isn't related to TestComplete or JScript, this is a common programming question, any developer could answer it. I suggest you to start learning basics of procedure programming (global and local variables, functions, passing parameters by value and reference), otherwise you will have to ask a lot of questions and get all of them answered in so much details.



    For instance, I will not spend time teaching anyone basic programming concepts, sorry. There are many tutorials and books dedicated to this. 



    Testing automation requires understanding programming, that's where you should start from.

Hi Sam,



You have a scope problem with your variable.



Try something like this:



Unit1:

var globalVar;


function setGlobalVar(value)

{

  globalVar = value;

}



Unit2:

//USEUNIT Unit1

function testGlobalVar()

{

  Log.Message("Global var value:" + globalVar);

  setGlobalVar(2);

  Log.Message("Global var value:" + globalVar); 

}



You should get the following log:

Global var value:undefined 10:39:26 Normal  

Global var value:2 10:39:26 Normal



Sincerely
