Filter Gallery2 based on selection in Gallery1

[b1t]

I'm trying to filter gallery items (to the right) based on selection in first gallery (to the left). When I pick a person to left the second gallery should show only incidents with the same ID. I created a search column called "RefID" in "Incidents" related to "People" that matches different persons based on column "ID" in "People". Can't get it to work..

The Filter formula in second gallery under "Items" is: 

Spoiler

Filter(Incidents, RefID=Gallery6.Selected.ID)

However it shows error on the first "(" and ",". 

First gallery = Gallery6 (data source: "People")

Second gallery = Gallery5 (data source: "Incidents")

How it looks when filter is on (previewing and selecting different people doesn't show anything on second gallery):

How both Gallerys look like when there is no filter:

Why isn't my label with ThisItem.RefID showing the RefID?:

   Please help. 😞

@b1t  what's the error u'r getting in the label with ThisItem.RefID ?

[b1t]

Kinda loose translation but something like:

"Name not valid. Identifier can't be found"

Shouldn't it work if the search column is called RefID? ThisItem.Date and ThisItem.Incident works as expected.

@b1t "Name not valid. Identifier can't be found" means it can't find that column in your data source. Try refreshing u'r data source. Looks like u'r in PA for Teams. Try closing and opening.

@b1t b'coz u'r using a Lookup, you need to change the RefID label to

ThisItem.RefID.ID

and the Filter formula in second gallery under "Items" to,

Filter(Incidents, RefID.ID=Gallery6.Selected.ID)

Hope this helps!

Please remember to give a 👍 and accept the solution as it will help others in the future.

It almost helped! You fixed the label issue, it now displays RefID correctly.

But the filter still gives the same error:

Translation: "Incidents = There is an error in the formula. Try changing it and run it again."

Does the OnSelect fields need something in the first Gallery? It's blank on Gallery (OnSelect) and Rectangle (the one you click) says OnSelect = Select(Parent). OnSelect is also blank on second gallery, only put in your filter formula under Items.

@b1t Set the OnSelect() of both the galleries to false (just to be safe). Could you tell me what is the data type for ID (in People) and RefID (in Incidents) - Are they Text or Number?

Well. You solved my orginal issue. I just deleted a bunch of left over buttons with errors (was using a template) and suddenly it started working without me changing any functions on the gallerys.

But now I decided to start again to use sharepoint lists instead of tables to enable attachments and I got the exact same problem again. The "(" and "," in filter formula shows error.

And THIS time the RefID Label only works if I write ThisItem.RefID.Value! The one you suggested ThisItem.RefID.ID Only shows numbers starting from 0 now. Like automatically assigned IDs I never asked for. I'm going crazy.
