    Hi Amparo,

    I got what you mean but unfortunately we do not have a feature that populates quantity via condition.

    This can only be achieved when you modify your form source code and inject custom script to perform such function.

    Let us know if you're willing with using your form source code and if you need assistance with the custom script.
