TezBox online wallet gives error on sending to tz1 address (solved!)


Successfully created my online TezBox wallet. All was straightforward and correct balance shows up in account. However, when trying to send a (small) test amount (100) of XTZ to Kraken, I get a popup error that says ‘invalid amount’ or ‘invalid number’. The solution that worked is that you (apparently?) must have a 0 in the ‘fee’ field. It is populated as null (or blank).
