Gallery - Items - Choice - This Data Type Is Unsupported For Evaluation

(0) ShareShare
ReportReport
Posted on by JS-11121644-0 4
In Power Apps i have created a Canvas App.
 
I have inserted a Horizontal gallery and I am trying to set the Items to: "Choices('Project Lists'.Department)".
 
'Project Lists' is a table i have in my current dataverse Solution. It is also located in the same Environment. 
 
The column [Department] in the 'Project Lists' table does use a global choice set, if this helps at all.
 
The formula I am using can detect the correct column, but it only results in errors saying: "This Data Type Is Unsupported For Evaluation".
 
How can I fix this?
 
Thanks,
 
Jordan

    What columns are you trying to display in the gallery?
    If you add Choices('Project Lists'.Department) to a variable does it show a Value column and is that what you are using in the gallery?

    This indicates that it is not the correct column.
     
    The formula I am using can detect the correct column, but it only results in errors saying: "This Data Type Is Unsupported For Evaluation".
     
    You should see a text column similar to this

    The table is correct, as seen below:
     
    And my column it seems like my column is correct, as seen below:
     
    But even though the data in that field is in fact of a Choice Data Type, the formula Choice cannnot detect the data inside. 
     
    Is my formula wrong? Or is the gallery the wrong solution? If I'm simply trying to pull a list of the unique values in this column in my 'Project Lists' table, is there something simpler?
     
    Ideally i would like to make the gallery option work because of the format i intend for other views.
