I can't reproduce the error, the behaviour you described is not browser-related.
However, it works with me both on Firefox and Chrome.
at the moment you can't add the number of bedrooms to search module.
Hi. I tried the page on my smart phone, and still get the same error? Are you clicking the link to my page first? I'm talking about where it says 'Prop ID and Price' just above search results - highlighted on screengrab.
