Re: Error when cascading third drop-down using one list

Hi @Anonymous,

 

Could you please explain a bit for 'cascad' the three fields?

The error message means some property you have specified would affect its own value based on the selection, which is not supported.

The error message mostly would be caused by refering to the editng control itself. Please verify the control name and make sure the proper control is correctly added.

 

Based on my understanding, here are three dropdowns, with each configured to Title, Building and Floor, and the Building is filtered based on Title selected value, Floor is fitlered based on Title and Building selected value, right?

If this is the scenario, then we could work with the Dropdown items with the formula below:

1. For Title dropdown, items property should be:

Distinct(SharePointList, Ttile)

2. Building Dropdown items property should be:

Distinct(filter(SharePointList, Ttile=TitleDropdown.selected.value), Building)

3. Floor Dropdown, items property should be:

Distinct(
         Filter(SharePointList, 
                 Title=TitleDropdown.Selected.Value, 
                 Building=BuildingDropdown.Selected.Value), 
         Floor)

Michael
