Combining Two MDX Select Statements

I have this MDX select statement that gives me the current year's data for the 'Sales Amount' and 'Customer Count' measures.

What I would like to have is additional columns with the previous year's data for the same measures.

I suspect I will need another select statement incorporating the 'prevMember' function, something like 'StrToMember(@pickTimeYear,CONSTRAINED).prevMember'. 

I have been unsuccessful with adding another select statement to get the additional columns for the previous year's data.

Thanks in advance for any suggestions.
