PBCS / Financial Reporting Web Studio

I have a column in a report which is populated by Year / Scenario / Period - with year and scenario driven by variables which are not the same as all other columns in the report.

When the column has no content I want to suppress.

Okay - easy - using - Column Properties / Suppression / If Missing Suppress - right?

But the bit I am struggling with is this column has two other calculated columns associated with it, Variance £, Variance %; and I want to suppress these when the main column is hidden.

Any way to do this please?

Column A - always populated

Column B (&Repyear, &RepScenario, &RepMonth)

Column C = Column A - Column B

Column D = Column C / Column A as a %

So Column B has Basic Option 'If Missing Suppress'

How to make Column C / D disappear if Column B is suppressed??
