Add condition assignment from excel document
I am wanting to assign participants to view one of 2 video stimuli based on a pre-existing group assignment. I have an excel document with participant ID (1 to 200) in column A and assignment (0 or 1) in column B. How can I get the 'assignment' variable to be recognised by OpenSesame so that in the Experiment Sequence I can add 'run if' instructions (e.g. [assignment]=1)?
