About set filter rules... (revit2018)

Hello, I am a beginner of REVIT API.
Recently I have been writing a code that applies the filter rules in a short time.

Works well if only one filter rule is applied, such as the first capture.

However, the code for implementing a second capture, for example, does not work.

If a user-defined level exists, the user has created a code to add filter rules for it.

Is there a problem with my code?

thank you.

private ParameterFilterElement Pvt_CreateFloorLevelFilter( Document doc, string filterName, double value )

{

ParameterFilterElement filter = null;

ICollection<ElementId> categories = new List<ElementId>();

categories.Add( new ElementId( BuiltInCategory.OST_Floors ) );

// Level Offset Value Paramter

ElementId param1 = new ElementId( BuiltInParameter.FLOOR_HEIGHTABOVELEVEL_PARAM );

// Level Parameter

ElementId param2 = new ElementId( BuiltInParameter.LEVEL_PARAM );

// Level of user select

Level targetLevel = _form.Transfer_SelectedLevel();

var miliValue = UnitControl.Millimeters_To_Feet( value );

IList<FilterRule> rules = new List<FilterRule>();

// Set rule Level Offset

FilterRule rule1 = ParameterFilterRuleFactory.CreateEqualsRule( param1, miliValue, Double_Epsilon );

rules.Add( rule1 );

// If there's user selected Level, add it

if ( targetLevel != null )

{

FilterRule rule2 = ParameterFilterRuleFactory.CreateEqualsRule( param2, targetLevel.Id );

rules.Add( rule2 );

filter = ParameterFilterElement.Create( doc, filterName, categories, rules );

return filter;

}

// If there's no user selected Level, apply only this rule

else

{

filter = ParameterFilterElement.Create( doc, filterName, categories, rules );

return filter;

}

It was solved by using "SCHEDULE_LEVEL_PARAM" instead of "LEVEL_PARAM".
Thank you.
