I am trying to allow the user to create a sign up system in which the user uses their phone number instead of their email. I used the built in sign up system but substituted the email for the US phone number and it seems to work. However now I’m trying to check if the user’s inputed phone number is already in use, and if so give them an alert. How should I do this?
NB: I am pretty new to bubble and while I think I have a decent grasp I may have missed something obvious
