Ok, so it looks like the Special_requests_and_conditions text area you have on the form has some spry validation applied to it. It seems that there is a limit to the number of characters that are allowed to be entered. The best way to edit this would be to select the spry element selection for that text area, it should be a blue tab around the text area. When it comes up in the properties window you should see the current configuration and be able to make adjustments to it.
