I am learning to use Designer 7 to build dynamic interactive forms for clients to fill in. Are there ways to Add Instances based on the value of data entered into a particular field. For example if a person enters YES then the instance occurs, but if the person enters NO then it does not.

Yes, this kind of interactivity is controled through JavaScript. Look at an of the Dynamic form examples and you'll see code for creating and removing instances of a sub-form. In all of the examples I've seen, the new instance is added when the user pushes a button. What you need to do is work the same code into a different trigger such as the "Validate event of a text field like this

// validate eventif(this.rawValue == "Yes")mySub.instanceManager.addInstance();
