syntax error on majority dollarsign lines in EXISTS article?

syntax error on majority dollarsign lines?

For example it is displaying as "EXISTS:A:$EXISTSMOD=NOTEXISTS" for my screen, and is throwing a parameter error.

Should probably be $$EXISTSMOD, $$OBJCODE and so on, as per example posts here:
https://experienceleague.adobe.com/en/docs/workfront/using/reporting/reports/text-mode/create-complex-text-mode-filters-using-exists-statements
https://experienceleaguecommunities.adobe.com/adobe-workfront-23/exists-filter-on-a-project-report-119091

Open help/reporting/intermediate-reporting/understand-exists-filters.md and inspect the EXISTS examples containing dollar signs. Compare them with the linked Workfront documentation and community example, then update the affected syntax so the article uses the documented parameter names. Done means the examples no longer trigger the reported parameter error.
