I can’t figure this out.

I’m trying to set a GLOBAL variable.  
ConfimIndex = 1

I want to be able to read ConfirmIndex from anywhere in the program(all screens)

I have tried system.util.getGlobal()[ConfirmIndex] = 1

But come back with a script error says  
ConfirmIndex has not been defined.

Can anyone help?  
Thanks

Can you just create a memory tag and reference that?

If you put the variable in project startup scripts and access them with full path (e.g. project.NewScript.blahblah ) it should work!

Try

```auto
system.util.getGlobals()['ConfirmIndex']

```

ConfirmIndex is treated as a variable without the qoutes.

Thanks everyone, I like the Idea of using a memory tag, but I will play with the other ways also.

I’m still learning so all help is greatly appreciated.
