    How to fix this error?

    For example, in a constraint you have defined a name for an variable
    linked to an object and/or a characteristic. This name is a reserved
    name, for example:
    DESK IS_A ... WHERE SIN = ..
    Certain names are reserved - for example, SIN for the standard function
    for sines.
    Rename the variable. You could do this by putting a query in front of
    the name, for example:
    ?DESK IS_A ... WHERE ?SIN = ..
