I have seen some conditional options that can be implemented, but I did not see one like I want. The closest example I can offer is a medical form.

Say you are asked to enter medications you are currently taking. If you leave the "No" box checked, no lines/fields appear to enter your meds. If you check the "Yes" box, then a line appears with the fields for medication name, dosage and frequency. If more than one med is taken, then clicking a "+" link or icon causes another line to appear. There could be from 1 to any number of medications. Can this be done in RSForm! Pro?

Conditional Fields refer to fields that are already existing on the form that you want to show or hide based on some conditions. What you are looking for is a way for the submitter to dynamically add an unlimited number of fields on your form.
While this isn't built-in, it can be done but it requires custom coding (Javascript and some PHP).

Okay, thank you for clarifying.

I have a form that was done a few years ago that may have what you want. If the user picks one of the 4 radio buttons (1 to 4 cars) it drops down the number of entries matching the request.
