ComboBox - Expected table value error

[Anonymous]

I have 3 fields:

Dropdown1.Items = "A", "B", "C"

These 2 fields are in the same card

TextInput1

Default = If(Dropdown1.Selected.Value="A",Parent.Default,ComboBox1.Selected.Result)

ComboBox1

DefaultSelectedItems property: If(Dropdown1.selected.value = "B",Parent.Default,Blank())

However, in the combobox1 im getting the following error message: "Expected Table value" since the parent.default value does not exist in the Combobox1 items (source). How do i fix this issue? 

Ps. This worked fine when i had a dropdown instead of a combobox, but due to the number of items i had to switch so the user could use the search function.

Hi @Anonymous 

I think the problem is more likely because the DefaultSelectedItems property expects a table value. This is because with a ComboBox, multiple items can be selected.

Therefore, for the DefaultSelectedItems property, I'd try something like this to see if it fixes the issue:

If(Dropdown1.selected.value = "B",
   Table({Value:Parent.Default}),
   Blank()
)
