Filter Function Returns Empty List to Combo Box

I have Gallery1.

Gallery1 has ComboBox1.

When I have ComboBox1 configured as follows the users can see ALL items in the Staking collection in the ComboBox list.

I have the need to filter the content of ComboBox1 by three parameters -
1. Role: Technician or Contractor
2. Cost Type: 'Subcontractor' or 'In House'
3. Location

When I use the following in the items of the ComboBox1 I can see all items sorted as desired above.

If(Role_DataCardValue.Text = "Contractor",Filter(Staking_Collection,Cost_Type = "Subcontractor" && Title =
Location_Dropdown.Selected.Value).Billing_Unit,

If(Role_DataCardValue.Text = "Technician",Filter(Staking_Collection,Cost_Type = "In House" && Title =
Location_Dropdown.Selected.Value).Billing_Unit))

However, the other users only see an empty expanded ComboBox1.

What am I missing?

Why does Staking_Collection.Billing_Unit allow the other users to see ALL items in the collection, but the filter formula only shows them the empty box below?

Hi @Phineas

This is a total guess here, but usually this happens because the user (dev) has permissions the others dont

Or because somehow the persons direct role impacts the filtering and isn't noticed until run time.

Also, normally when you are doing multi-filtering etc like this you write your code a little differently

SortByColumns(Filter(ManageUsersUserList, (IsBlank(MyCmb1.Selected.Value) Or Role = MyCmb1.Selected.Value) && (IsBlank(MyCmb2.Selected.Value) Or Role2 = MyCmb2.Selected.Value) ), "MySortColumn", SortOrder.Ascending )

Give that a shot and let me know if it helps.

Also you can check to see if you are getting any weird errors by doing the following

Step 1. Close your App (stop it running)

Step 2. Click the Stethoscope in the Top Right

Step 3. On the bottom click Open Monitor

Step 4. Once Monitor is running go back and run your app

Step 5. Cause your issue to happen

Step 6. Close the app

Step 7. Go to the Monitor and Filter (top right) based on Error, or key word. Go to the line or lines that match this

Step 8. Look at the Response Tab and you will have to expand the Body > and the Header >. Then look at the body to see more details on the error
Do this for each line you find

Step 9. On each line, also check the Code being executed on Tab 2

If I have helped you, I would really appreciate if you please Mark my answer as Resolved/Answered, and give it a thumbs up, so it can help others

To be clear the Combo Box works for me, but not others.

On Screen1 is Form1, which has Label1 that contains content that clarifies whether the user is a 'Technician' or 'Contractor'.

Label1 has the following formula -
LookUp(Technician_and_Contractor_Collection,Full_Name in Tech__Contractor_Name_Fld_DataCardValue.Text,Role)

Below is the Monitor and a screenshot of the app when I use the original Combo Box. This is the Combo Box that shows as expanded but empty for others. There is no error associated with the use of the Combo Box.

The formula in the test Combo Box is -
If(
(Role_DataCardValue.Text = "Contractor"), Filter(Staking_Collection,Cost_Type = "Subcontractor" And Location_Dropdown.Selected.Value in Title)).Billing_Unit

Below is the Monitor and a screenshot of the app when I use a test Combo Box. There is no error associated with the use of the Combo Box.

The following is for a test Combo Box. It is returning the correct data, but it is not distinguishing whether the user is a 'Technician' or 'Contractor'; consequently, all users would see the same data - which is NOT the desired. Combo Box outcome should be based on user type and location chosen.

The formula in the test Combo Box is as follows -
Filter(Staking_Collection,Cost_Type = "Subcontractor" && Location_Dropdown.Selected.Value in Title).Billing_Unit

My formula was fine.

It was a name formatting issue in the data source.
