Hi friends,

I know Services in App inventor is in an early experimental phase, many components do not work. errors, bugs, crash... but we can try and learn.

You know experimental Services in: http://services.appinventor.mit.edu/

Introduction to  Background Services and Tasks in App Inventor:

I am translating the documentation into Spanish:

But this is my question, how into a variable in Clock1.Timer?

When a global variable (x) is in Clock1.Timer, app crash.

This is my trick, use a Clock2.Interval as global variable.
