RDL reporting expression for multiple Boolean

Hello ,

I want expression for below scenario in RDL(SSRS) reporting Expressions.

Columns Australia, Austria, Brazil, Canada and China are Boolean

I want to show "Australia, China" when both columns are true

Current the formula as below:

=Left(
  IIf(Fields!crms_australia.Value,"Australia, ", "") &
  IIf(Fields!crms_austria.Value,"Austria, ", "") &
  IIf(Fields!crms_brazil.Value,"Brazil, ", "") &
  IIf(Fields!crms_canada.Value,"Canada, ", "") &
  IIf(Fields!crms_china.Value,"China, ", ""),
  Len(
    IIf(Fields!crms_australia.Value,"Australia, ", "") &
    IIf(Fields!crms_austria.Value,"Austria, ", "") &
    IIf(Fields!crms_brazil.Value,"Brazil, ", "") &
    IIf(Fields!crms_canada.Value,"Canada, ", "") &
    IIf(Fields!crms_china.Value,"China, ", "")) - 2)

Would I know is that any better idea to get the countries from field?
