changed variable units to unitz, because this is already defined.

Fixed the geogebra_applet() parameters to call the scaling functions.  Issue was geogebra accepts abs() but not Abs()

The geogebra_applet() function is called directly in the statement, and the diagram resumes.

The geogebra_applet() is also called and stored in a variable ggb_diagram to be used by the marking algorithm.

The custom marking algorithm fails on 'evaluating variable right_sign' after resume

Currently using the applet variable.  doesn't resume, but marking works.

This demos the problem.    Three methods of loading a ggb applet compared.

1.  uses javascript function Most complicated method, but reloads and can call click script to rescale

2.  Defines a variable.  Doesnt reload, can't call click script to rescale

3.  directly loads geogebra_applet()  Reloads, but can't call click scripts or get values from the applet

  Tried to revert to geogebra_applet() method with parameters, but couldn't make it work.    Restoring to previous version... geogebra_function() attempt.

This version uses javascript extension function geogebra_function()  and does not resume properly

Fixed some sign errors in the advice.   Should be correct now.

Changed gaps to engineering accuracy with units, where units are specified as "".  Should edit question to use actual units.
