Is the following sentence correct to decline a invitation?


あ、実は今日、会議があっているんですよ。

This as an answer for an invitation to do something today. Also the dialog I'm
talking about is over the phone.




If you're asking if this is the correct way to decline an invitation, then
yeah you can say that you have a meeting today as a way of saying "no I'm
busy".

If you're asking if your sentence is grammatically correct, then no, not
completely. While あっている is used in some dialects, it's not standard Japanese
so you should probably use ある.
