Search Results: going down on me take back

I want genuine answers but basically I work at an Amazon building and 2 weeks ago I saw this super cute girl. so then the following Saturday specifically on September 19 when I got to work my boss sent me to opposite side of the building of where this girl worked. So I was pretty annoyed with that but about 10 minutes in to the shift my boss comes back and tells me to go to the other side of building (where the girl was). So when I get there that boss tells me to go to a specific wall to pack boxes so I go there and just so happens that out of 28 different walls I was put on the same wall as her. So about an hour later that boss comes by and chats with me so I ask if he knows her name and tells me he will find out and tell me. But better yet comes back and moves me right next to her. So for the rest of the day i would strike up little convos here and there with her. Planning to ask her out at the end of the day. So at the end of the day i ask "I want to take you out sometime. Cause I think you are cute" and remember its amazon so its loud usually and masks are required so she says something can't really make it out then I hear her say take my ohone number down. So I take out my phone and type her number in when she gets to the second half of her number she stumbles a bit. Then at the end of the shift before she leaves I asked her if she texts just to make sure I could text her. She says yes. And when she actually leaves she says bye to me. The next day I was going to text her but I got the invalid number thing from my carrier. So for bad grammar. But my main question here is did I get the number wrong? Or was it on purpose? Should I approach her on Saturday again and tell her I may have gotten the number wrong. Also one last point is she is shy and doesn't have any friends at work to my knowledge.
