Dude, you have big problems with site today. Was fine at 1am...could enter my info and my phone number without issue. Decided to wait to sign up for vaccine until today.
Now, at 9:20am, have to use arrow keys to enter phone # because cursor moves to the 'left' of the first entered number instead of the 'right'.

Next, and the biggest issue, I used the 'previous' button and it took me back to the name/address page and someone else's info was there in the name field. so my address was there, but someone named Monica something or other and HER dob etc was in the top seciton instead of mine. That is really really bad and you need to get it fixed.
I re entered my name and info and moved forward to finally sign up.
The other issues are numerous. Here are a couple of big ones...first...you have to only enter the zip of the location you were invited to or you get no locations (and I live within 20 miles of the location).
Second: at 9:20a today the date field wasn't working...it said there were no events for the 29th ..and later when I was finally able to get off the page there were tons. When I changed the date and I clicked next it kept telling me to select a location, and a location was selected.
