Getting error message when executing a case when query

I am trying to transpose data from a view into a different format. The current data is not taking into account the year, only the month. The query I wrote is below and is failing to execute. The columns have a prefix e.g v2.sales_boundary_level is QL Chair v2.sales_boundary_level. How can i modify this query?select v2
.Sales_Boundary_Level ,v2
.Territory ,v2
.Region ,v2
.Area ,v2
.Division ,v2
.ProductID ,
sum(case when v2.months = '2010, Month 1' then v2.value else 0 end) as Jan_Plan,
sum(case when v2.months = '2010, Month 2' then v2.value else 0 end) as Feb_Plan,
sum(case when v2.months = '2010, Month 3' then v2.value else 0 end) as Mar_Plan,
sum(case when v2.months = '2010, Month 4' then v2.value else 0 end) as Apr_Plan,
