SUM with a condition

Hi, I checked multiple posts but have not been able to arrive at the correct formula.

I have a table (sales of vehicles over last 10 years) with a Sales column. I have created a measure called TotalSales.

Now, in the table, i have another column which classifies the car types as either Mainstream or Premium.

I created following DAX formula:

TotalMainstream = CALCULATE([TotalSales],'SalesData-UAE'[TYPE]="Mainstream") -> this just gave me TotalSales Again

 

Tried couple of variations of SUMX as well, did not seem to work.

Attaching the screenshot.. pls let me know.
