Passing on variables to expressions make more dynamic selections

[#1]

I have several fields that are similarly named: "BudgetForecastToday, BudgetForecastYesterday, BudgetForecastLastWeek, BudgetForecast30Days, etc."

I was wondering if there's a way to pass these onto an expression, like:

=sum(BudgetForecast + $VARIABLE)

of some sorts.

Is this possible?

Yes. You can try it with a small syntax correction.

=sum(BudgetForecast+$(VARIABLE))
