Formatting Currency field in SSRS Fetchxml report

I have a currency field "totalamount" which is set to Currency precision 4 places at CRM level. While displaying this field in my Fetch xml report, I want to show only 2 decimal places.

I am using this expression inside the textbox: [Fields!totalamount.value]. It now displays as €‎800.0000

I tried all the below options so far, but none of them are working..

1.  Format (Fields!totalamount.Value,"C")

2.  Textbox properties, set currency format to 2 decimal places.

Please help!
