Hi @Paul.Hardwick1. Unfortunately, even though iLogic forms are fairly easy to create & use, there is still very, very little you can do from an iLogic rule, to access or edit an iLogic Form. About all you can do from an iLogic rule, related to iLogic forms is show one, list their names, and set one setting about size & position saving. There are other types of Forms (VBA UserForm, Windows Form) that are more dynamic and changeable from code, but those other options are also a lot more complicated to use, if you're not familiar with them.
There are also some differences in form functionality between a 'local' (saved in a document) iLogic form and a global iLogic form. Local forms can immediately react to local changes, and can cause immediate reactions locally. There is one little trick you may be able to use, if it is a local form, that may allow you to use two similar checkbox items in your form, with two different labels, then only have one of them available, depending on another parameter's value. In your posted image, while you have that parameter line item selected (representing the checkbox), you can see its properties & settings in the area below. You'll notice under 'Behavior' is one called 'Enabling Parameter Name'. If you set-up another (one or two) True/False type user parameter that is True when you need the "RH" version, and is False when you need the "LH" version, you could use this other parameter within that 'Enabling Parameter Name' control, to dictate when this line item will be available, or greyed out. If set-up right, you would then have two line items (checkbox) for the same parameter, but both have different labels, and only one will be available to the form's user when it is launched, based on those other parameter's values.
