How to only display a record that has many choices

[patty789]

Hello,

I have a combo box displaying plan numbers and i want to only display the elevation associated with that plan. So when the user selects the plan the other combo box will only show the elvations choices. No sure if i need to use a filter or a lookup.

I would suggest using the FILTER function because it can return many values (i.e. elevations) as opposed to LOOKUP which can only return a single value.  Put this ocde in the Items property of your combobox.

Filter(your_datasource_name,Plan in ComboBox1.SelectedItems.Plan)

My solution assumes your 1st combobox is storing the plan in a column called "Plan".

I updated my answer.  It seems we were both typing at the same time.

Filter('Plan and Elevation',Plan in ComboBox6.SelectedItems.Plan);
