SSRS Dynamic Parameter--Show different Values

I am new to SSRS. I have no idea to show different values from a certain column. The lab's requirements are as follows:

Data Source: AdventureWorksDW2012
Design Report dataset query use Following Tables:    Select Top 200 records
dbo.FactInternetSales ,dbo.DimProduct , dbo.DimProductSubcategory , dbo.DimProductCategory 

Requirements for report:
A)Fields display on main report:  
      EnglishProductCategoryName AS Category
        , EnglishProductSubcategoryName AS Subcategory
        , EnglishProductName AS Product

B)Display  SalesAmount, TaxAmt, UnitPrice  dynamically based on selection of parameter  “Display Column”
C)create parameters: 
Parameter: “DisplayColumn” --control the forth column to show  SalesAmount , TaxAmt or UnitPrice  

Parameter : “Hide Title” -- Control the display of Report Title

Do I need to create 3 reports?
