    94 Invalid use of null

    [edited from support email]

    I am receiving an error message that says "94 Invalid use of null"
    when I attempt to start one of my medialab experiments. I have
    several other experiments that run properly on Medialab. I cannot
    figure out what is causing this error message to occur, can you help?

    Check all the questionnaire files for a blank item, or an item with missing
    parentheses on the parameter values. If you can't identify the problem,
    please send us the que files we'll take a look at them.
