online check out button for classes not taking address

[asgj]

I ran a search but could not find this issue. I am attempting to create a button for purchasing a class. When I select location as in-person, it opens the address box. I input the address, but it is not accepted. There is no drop down box, and I can't figure out what it wants. Because the system won't let me proceed without an address, I can't create the button. Has anyone else had this issue, and if so, how did you resolve it? Thanks. 

I tried to attach a screen shot but apparently I do not "have permission to upload images."

A quick reply - I found the problem.  When using Firefox, there is no option to select an address from a list. This is why it will not take. I switched to Safari and was able to complete the task. I haven't tried it, but I suspect Chrome might work as well.  Posting here in case it helps anyone else.
