Using conditions you can dynamically check for responses and decide whether to invoke a particular processor or not .This can be configured in the Processor Editor page. If there are no conditions the processor will be executed always.

If you want a user to submit the form only once then you can use this feature . Or you may want to customize your emails based on whether the form is submitted first time or not .You should use a cell phone number , email id , or employee Id that is unique to find out if its a duplicate response .

Important

Things to keep in mind

 If you want to send two different emails when the form is submitted first time and for subsequent times then you have to use two processors and two duplicate conditions . Select the condition "Is not Duplicate" on the appropriate question to satisfy for the original response , and select the condition "Is Duplicate" to satisfy for the duplicate response.

Use Cases

 This feature is extremely useful if you want to send emails only for first time form submitters ,trial periods, one-time and temporary discounts, reservations, limiting access to information, among others.

At this point not all the question types can be used with conditions.Please note that only the following question types can be used with in conditions.

• If a particular question is part of the form and condition and is deleted later from the Form , it can cause unwanted consequences. Please test your Processors properly when adding or removing fields in the form or in rule conditions.
