The ticket portal has been extensively tested on many devices & platforms but not perfect.
If you're experiencing an error, apologies for this and thank you for your tenacity!
These are known solutions:

1) Facebook links. If you've clicked onto this site and are within Facebook's web browser, it is limited and can't handle the ticket WebApp. Please open your separate browser app and type in this address:
wausauspace.org 

2) Windows users: Clearing your browsing history (as a good regular practice anyway), has instantly solved Windows platform errors.

3) Below is a crude Google Sheet with current seat availability and ticket links.
While not very professional, it is an alternative solution.

4) Google services may be temporarily down. It's rare and usually for only a short time.
