Square won't accept my routing number

[jewelrylady7]

Square will not accept my routing number from my walmart debit card account. Other places have accepted it as good so why won't square? I don't want to get a different account just for this.  any ideas? its 9 digits just like any other routing number

I've read on other posts that prepaid type debit accounts are not supported. You may only use transactional bank accounts so that refunds as well as sales are accepted.
