How to have a table show a message unless a slicer is selected for data with text values

[indigodiv]

Hello everyone,

I'm new to Power BI and I want to create a table visual that shows "To view notes, please select an area from the area slicer" unless an area from the slicer is selected, in which case it will show the notes. 

I have a table of Areas, and a table of Notes that contain comments about visuals in the area. I am attaching screenshots of the data and the relationship between them in power bi here: 

The Areas from the Areas1 table is connected to the Areas in the notes table via a many to 1, single cross filter direction. 

In Dax, I created two measures: 

1. Filtered Area = Calculate( Isfiltered (Areas1[Areas]), ALLSELECTED(Areas1[Areas])) 

2. Notes Measure = IF( [Filtered Area] = TRUE, values(Notes[Notes]), "To see notes, please select a Service Area from the Service Area Slicer")

I then dragged the Notes Measure into the values field of the table. 

When nothing in the slicer is selected, the table appears to work the way I want it to: 

However, when I select an area, I get an error instead of the table displaying the notes (screenshot attached below):

 Why doesn't the dax work and how can I fix it? Thank you!

Hi, @indigodiv 

Since there are multiple notes in one area, you cannot get the correct return result.
Try to modify the measures as follows:

Notes Measure = 
IF( ISFILTERED(Areas[Area]) = TRUE, CONCATENATEX(values(Notes[Notes]), [Notes],"; "),
    "To see notes, please select a Service Area from the Service Area Slicer")

Result:

Please refer to the attachment below for details.

Hope this helps.

@indigodiv , you have to create measure like

if( Isfiltered (Areas1[Areas]), [Measure], blank())

Thank you for your response!! Would this new measure  be in addition to the two other dax measures I wrote? What does this third one do?
