When there are multiple Crosstabs on a single report, and you simply
want to add an additional column to the Crosstab, ALL other Crosstabs on
the report cease to function correctly again unless the crosstab causing
the issue is removed, and re-added once again (or you remove the column you are attempting to add). In this scenario, I want to add a "calculated column" to the Crosstab which displays whether or not "a question was answered". It works absolutely fine in the first cross tab (see the Designer screen shots), however, attempting to do the exact same steps on a 2nd Crosstab causes the report to be unreadable.
