This table provides the parameter types for a lab that enables equations.

                  Parameter Type for the Lab

                  | Total Value Equation

                        -  Equation Total - Fires only at the formula
						level. The parameter is not visible at the item level. 
					 
 
                        -  Rollup, Cost, and Informational - not
						applicable. Always add the Total Value Equation parameters to the lab as
						Equation Total.

                  | Calculated Parameter 
				 | 
                   
				                 
                        -  Rollup - Fires at the item level. The
						equation is ignored and the parameter rolls up according to the rollup rules at
						the formula level. 
					 
 
                        -  Informational - Fires at both the item and
						formula levels. 
					 
 
                        -  Cost and Equation Total - Not applicable. 
					 
 
                       
				               | 
               
               
                  | Rollup Param Total Test 
				 | 
                   
				                 
                        -  Rollup - Fires at the formula level, not
						the item level, but does not assign a parameter value. (In other words, if you
						assign a value to 
						
Context.ReturnValue, it has no effect.) The
						Equation Indicator is typically used for an equation that tests or acts upon
						the rolled up value in some way. The parameter behaves like an ordinary rollup
						that has no equation. 
					  
                        -  Cost, Informational, or Total Value
						Equation - not applicable. Always add the Rollup Param Total Test parameters to
						the lab as Rollup.

      For Parameters added to a Lab as Cost: When these parameters have an
         equation attached, the equation is ignored.
