Conditional Logic Causing Scripting Error???

I am in Firefox 11.0, using the Beta version of Gravity Forms (1.6.4), and version 3.3.1 of WordPress. I am using a lot of conditional logic and calculations based on a guest count (entered on the first page) in a multi-page form. I am getting scripting time-out errors as well as problems with the form freezing when playing around in a preview of the form (I haven't yet integrated it into my site's template since I'm still testing). Could this be caused by the Beta, or the amount of fields with conditional logic/calculations, or something else? Are there any best practices to use if I want a number entered in the beginning of the form to be used to calculate many fields throughout the form? I would rather not have the user enter the guest count for their event as a quantity for each item if at all possible, but will do it if that will solve the freezing/scripting errors. Any help you can give me would be much appreciated!
