Hey @serena_zadoorian,
As previously mentioned the TextBox component is a work in progress still. While we iterate to address the issues that prevent the online version of your study from running as expected, I have edited my forked ‘New.js’ to behave like you describe: a new TextBox component is created on each trial, at the end of which the typed in value gets saved in the ‘textbox.text’ column.
I hope that’s something you can use for now, here to help if not and again many thanks for your patience
