How can I clear the current page (user input and a table) and display a new form?

Thank you for the response. I tried this and and I receive the following:

“Cannot read property ‘then’ of undefined line 41”. If I comment out the “.then”, statement, it appears to work ok.

//     . then ( **async** ()   =>   { 

I am looking into this, but all this about promises and such is a little over my head. I’m just getting started with java…
