信用卡已扣款， 因为有一个过程，建议等几天再确认一下。BTW， 我自己没投过付费期刊

支付成功的话，最后一栏会变成paid invoice，我前两天刚中了一篇，交了钱。

我投过，当时填好信息付款后就收到电子invoice了

我也投了这个杂志，编辑叫我发以下四项的任何一项，以下四项是什么意思？作者单位吗？
1.An Institutional email address.
2.Link of an institutional website that shows the email address.
3.Previous publication that shows the email address.
4. Letter from institution (e.g. Head of Department) confirming position at institution，
