I had asked a question earlier and here is the link
http://www.experts-exchange.com/Microsoft/Development/MS-SQL-Server/SQL-Server-2005/Q_23496475.html

since then the requirements have changed
The user wants the capability to select All Orders, Only Valid Orders , or Exclude Invalid Orders.
Valid values for the parameter @Check = 'true', 'false' or 'all', for which I have added a radio button on the screen instead of a checkbox that I had earlier.

Default value of @Check = 'all'.
The function fn_CheckValid accepts an input of string and returns 0 or 1, based on whether the order is valid or invalid

My current AND condition in the select clause handles only the true or false condition
select .....
And (@Check = 0 or (fn_CheckValid(strOrder) = @Check))

I think you have got your data type for @Check muddled; is it a BIT or a string type? You might need to do some type conversions

You only seem to have two options here. "All Orders" (ie Valid and Invalid), or "Valid Only".
Your third option of exclude invalid is surely the same as "Valid Only"

Anyway, the logic you need is '
WHERE colA = Colb
.....
AND (
      (@Check = 'all')
OR
      (@Check IN ('True', 'False')
      AND (fn_CheckValid(strOrder) = @Check))
      )
      -- Looking at your previous post, this is probably how you should code the line above
      AND (select case when dbo.fn_CheckValid(strOrder)  = 1 THEN 'True' Else 'False' end )  = @Check))

That way, if @Check = 'all' then you won't call the function.
