Indesign cc2017 page size script

[attil]

I have this script to generate a page size using variables. If i change the page size, i have to manually run the script. Is there a way to have the script run when i open the document and if i make changes to the sizing? Any help would be greatly appreciated.

var doc = app.activeDocument;

doc.viewPreferences.horizontalMeasurementUnits = MeasurementUnits.inches;

doc.viewPreferences.verticalMeasurementUnits = MeasurementUnits.inches;

var w = doc.documentPreferences.pageWidth,

    h = doc.documentPreferences.pageHeight,

    pagesize = app.activeDocument.textVariables.itemByName("PageSize");

pagesize.variableOptions.contents = h + " in X " + w + " in";

Thanks, so much for the help, Trevor. Just one more question. How can i add a Bleed/Live size variable? I don't think it was answered in the post.
