So yesterday I tried to set up a date the other person said "How about tomorrow night? , It is is free for now (depends on work)"

To which I replied later on in the day "yeah sounds good. Let's meet at X time at X place. What's your number just easier to communicate"

It's today and there is no response. Reason I asked for her number is for her to message me if she gets busy at work. I decided to leave work early just in case. Anyways did I do anything wrong? I feel like I have.
