Hello everyone!

 

Thank you for reviewing my question.

 

I am building my first app where the first step is to collect simple text information from user, plus choosing from a dropdown list, to create a collection, display the collection as a table, and then perform some calculations on the table.

 

I made a "test" app using the example found here: https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/create-update-collection 

 

OnSelect for the button control is:

 

Collect(
ProductList,
{
Product: ProductName.Text, **ProductName is a text input box**
Color: Colors.Selected.Value **Colors is a dropdown list**
}
)

 

Following this example, my app has a collection titled RadList and columns titled Room and Type.  Room collects text input from user and Type collects a selection from a dropdown list (just like the example above).

 

The OnSelect for my button control is:

 

Collect(
RadList,
{
Room: RoomName.Text, **RoomName is a text input box**
Type: ChooseType.Selected.Value **ChooseType is a dropdown list**
}
)

 

However, I am getting an error.  When I go through my function both "RoomName" and "ChooseType" show "This data type is unsupported for evaluation".  

 

What am I doing wrong?  Am I missing something?

 

Thank you for your time and assistance!

    Hi @suzinger 

    How are you determining the items in your Dropdown.  If you are using Distinct(datasource,Column) your Type: ChooseType.Selected.Value  should be Type: ChooseType.Selected.Result.

    The dropdown list is populated by an Excel table.

    Ok, so I changed my dropdown.  Instead of populating it from an Excel table I simply set the dropdown values in the Items property and now it works.
