How to make it cross the last data?

[FrESM]

I need help with this. I have this scenario: a client is on a call with a virtual agent at my work and asks to be connected to a supervisor or someone. This triggers the scenario. An email is sent with the case details, the client’s name, and the client’s number so they can call them. This is then sent to an Excel spreadsheet. My problem is that in the middle of the call, the client can make a mistake when giving their number. I don’t know. The last number changes from 4 to 7. This causes two emails to be sent: the first with the number 4 and the second with the number 7. What I want is for only the last one to be sent and not two emails. Thanks in advance.
