sidebar widget holiday booking engine problem

Hi,

Hopefully someone might be able to shed some light on the following issue for me as it doesn't appear to be an issue with the plugin (sunpress) as this works within other themes.

When you submit a holiday search using the booking engine in the left sidebar it brings back the results within the main page, which is fine; however it also copies whatever appears within the left sidebar underneath.

Could anyone offer any suggestions on how I could fix this?

Thanks
Joe
