Why it is showing error while adding column in the customized form

[yougan]

I am trying to add column in the screen, but when I tried to add below highlighted  column (ProductKey) . refer C1 screenshot

getting an error refer screenshot C2.

why it is picking up product key not ProductKey   ( with spaces) 

How Can I add ProductKey  column?

@yougan ,

The error is when you are trying to set a Default to a multi-select field.

You cannot do this on this type of field as it is expecting a Table. The DefaultSelectedItems is what you need - here is a useful post.

What is meant by  default to multiselect field? I am not clear on this.  Can you please elaborate here?

what is the multiselect field here?

what is the default here?

@yougan ,

As below - you need to leave the values alone and Power Apps will take care of most settings when you add the card. You have changed or added the Default. Your control can select more than one value, therefore the field is a Table, (more than one row and more than one column). You also have two separate fields - 'Product Key', which is Text and ProductKey, which is this one. They are both available to add to your form if required.
