How can I use logic with a hidden field?

I have a dropdown field named "Survey Type". I have 1 survey that differs slightly based on the Survey Type (72 Hours & Post-Discharge). I am passing the survey type parameter through a URL & I want to hide the question & use logic on the field to determine the available questions for the survey. However, I can not seem to pass the parameter to the field because it has logic. Is this a limitation of Smartsheet or is there a way to do this... I guess I could always create two surveys but I'd rather not.
