BackBlaze Trouble

I have a Mac running Catalina. I tried to buy the backup protection in BackBlaze. The payment info was presented in a table. I could not select the right plan or enter any credit card info. I tried with quick nav on and off.
I have run into this problem on other sites. Is there a secret to typing in those tables?

What I tend to do is tab

What I tend to do is tab between those fields, failing that you can call aira and hook in with team viewer and they would be able to put the curser where it belongs and you can type in the fields. I hate those table things as well. I just dealt with that on a windows site that was completely inaccessible.
