Alright, when you set the variable through the exposed input parameter in the Create Widget, you’re already assigning the value to Sample Text. So you don’t have to set it again during the Event Construct.
Instead what you’d want to do is take the “Sample Text” variable (which already has the value you passed during Create Widget), and pass it as the input for the Set Text node using your “Sample Display” text block. This way, you’ll be overriding the default value of your text block with the one from Sample Text.
