Hi there,
I’ve had what may be a similar issue trying to add textbox2 to my experiment. No buttons here, but anyway it looks like the OP’s error is has something to do with textbox2 as well.
EDIT: My solution was to add a space in the default text for my textbox; this got rid of the error. Also, changing the units from ‘norm’ to ‘height’ might help (see this thread)
