Hide a specific pick list Value based on two previous pick list field

Question

I'm working to find the way how to hide 1 of the 3 values from my pick list field, based on 2 different previous value content...

I have a field "length" (picklist 9, 18, 36), field "width" (picklist 1/4, 3/8, 1/2, 3/4, 1) and field "material" (x, y and z ). I would like to filter the field "length" based on Material_Field and Width_Field, so as described below:

The code below is running, but there is still a problem... the pick list behaviors is well, but when I saved the record I'm losing the value, so my goal is save the pick list's value in to the custom field Long_Imperial__c, has somebody worked on this?... Can somebody give me a hand??? Controller public string select_length {get; set;} public string var_length {get; set;} public string var_width {get; set;} public List getListWidth() { List options = new List { new SelectOption('','-- Width --') }; for(Schema.PicklistEntry gr:Customer_s_Price_List__c.Wide_Imperial__c.getDescribe().getPicklistValues()) { options.add(new SelectOption(gr.getValue(),gr.getLabel())); } return options; } public List getlength(){ List options = new List(); var_width = cpl.Wide_Imperial__c; if(var_width == null) return null;{ if(var_Product_Type =='Laminated / + 10'){ options.add(new SelectOption('9','9')); options.add(new SelectOption('18','18')); } if( var_Product_Type =='Plasma' && (var_width =='1/4' || var_width =='3/8' ) ){ options.add(new SelectOption('9','9')); options.add(new SelectOption('18','18')); } if( var_Product_Type =='Plasma' && !(var_width =='1/4' || var_width =='3/8' )){ options.add(new SelectOption('9','9')); options.add(new SelectOption('36','36')); } } return options; } Visualforce Length (Yards)
