when running code in visual studio 2012 gives me error error cs0037: cannot convert null 'decimal' because non-nullable value type

>error cs1061: 'decimal' not contain definition 'value' , no extension method 'value' accepting first argument of type 'decimal' found (are missing using directive or assembly reference?) 

c# case-sensitive language. need capital v in value. , tostring needs camel case. allow code compile.

@auction.currentprice.value.tostring("c")
