Often your forms will need to make a decision, whether that is to decide if a customer can continue with their submission or to determine how much the customer should pay for a service based on the questions they've answered. Other examples include being able to compare customer responses to known values or convert values to enable interoperability between different applications. Every form will require different decisions to be made.
Conditional logic allows you to make these decisions using IF/ELSE style logic within the control centre. Using a combination of AND/OR and ELSE's complex logic can be built and used in your forms for a wide variety of different use cases.
