Help with Setting Previous Month Date Parameter for SSAS via SSRS

Question

Hi All,
Firstly, any assitance is greatly appreciated.
Now, I am working on developing a report for a business area that will be sent on the first of every month. The report will contain data for all records created in the previous month, current year.
I have been able to successfully implement a default year parameter, which will default to current year-
="[REFERRAL LODGEMENT DATE].[CAL YEAR].&["+CSTR(Year(Today))+"]". However, when I attempt to set a previous month paramater it is not setting when the report is generated. The code I have used
is as follows: 
="[REFERRAL LODGEMENT DATE].[CAL MONTH NAME].&["+CSTR(Month(Today)-1)+"]"
Cheers

Before you spend more time trying to fix the parameter, let me suggest that you can write MDX to come up previous month data.
if you can't go that route, couple of things to consider for your approach:
1) don't subtract 1 from January that won't work. you'll need to handle it using the ssrs expression.
2) when you use the month function it's going to return a month index so effectively you are passing something like [REFERRAL LODGEMENT DATE].[CAL MONTH NAME].&[7] to SSAS, is that the current format?
you can use the MonthName function to get month names but again make sure that the formatting is right.
to see the parameter value, you can display it on the ssrs report and see if it's the right format.
