Problem with dynamic sql statement

Can someone tell me why this is not executing properly. No error
messages, just no rows returned. I need to have an output parameter
and a return value.
Thanks in advance

CREATE PROCEDURE dbo.sel_LookupChar
(
@.Lookup_Value NVarChar(30),
@.Lookup_Field NVarChar(30),
@.Lookup_Table NVarChar(30),
@.MyOutput nVarChar(100) OUTPUT
)
AS
Declare @.SqlStr VarChar(1000)
Select @.SqlStr = "Select " + @.MyOutput + " = " + @.Lookup_Field + "
From " + @.Lookup_Table + " Where " + @.Lookup_Field
Select @.SqlStr = @.SqlStr + " = '" + @.Lookup_Value + "'"
Exec(@.SqlStr)
return @.@.rowcount
GOUse ' not " for string delimiters.
Also, try PRINT @.SqlStr instead of EXEC, and show us the result.
