- First, in the automation flow, we request the client to provide their height and weight.

- Next, we save the client’s responses in the variables
payload.height
andpayload.weight
.


- In Execute JavaScript, we use the variables
payload.height
andpayload.weight
to calculate the client’s BMI and suggest the most appropriate size based on this information.

- Finally, the result of the code will be saved in the variable
payload.suggestedSize
, which is sent to the client in the last message indicating the suggested size based on their height and weight.
