A positional parameter cannot be found that accepts argument

I’m trying to fire up my first dashboard, using https://poshud.com/PowerShell-Universal-Dashboard as an example.

None of my input components are working. For a textbox, I’m getting the error:

`A positional parameter cannot be found that accepts argument ’ (New-UDTextbox -Label ‘Standard’ -Placeholder ‘Textbox’) '.

Within my dashboard code, it looks like:

New-UDTextbox -Label 'Standard' -Placeholder 'Textbox'
