Thanks DOP2000,

That worked perfectly. Wish I had known that

a few days ago.

Thanks again!

I am creating a game to create math problems. I pass the number of digits for each operand plus the operator (+,-,x,/). The script generates two random operands and the adds them (for now).

Here is the calling sequence:

runtime.globalVars.ans=genproblem(runtime.globalVars.n1Digits,runtime.globalVars.n2Digits, runtime.globalVars.operator);

The header for the JS:

function genproblem(n1digits, n2digits, operator)

It does what it is supposed to and returns the sum of the two numbers. I also need the two operands stored in C3 global variables in order to display the entire problem.

I read this:

globalVars

An object with a property for each global variable on an event sheet in the project. For example if the project has a global variable on an event sheet named Score, then runtime.globalVars.Score provides access to the global variable from script.

In some cases, event variables may have names that aren't valid JavaScript identifiers. In this case you can use the string property syntax, e.g. runtime.globalVars["Score"].

I added the following:

runtime.globalVars.n1 = n1;

Then I get a runtime error:

action.js:31 Unhandled exception running script Event sheet 1, event 1, action 2: ReferenceError: runtime is not defined

So the question is how do I update global variables from a script file?
