Catch Everest – Slider Text

Hi, This is first time I have used wordpress and have managed to get catch everest theme running.   It was because of your detailed documentation and forums that I have been able to set up different widgets also and test out the bilingual RTL settings by modifying the rtl.css. Problem: The problem is basic I'm sure and I may be missing something, but when I change the text on the main slider, it does not reflect the changes that I made in the catcheverest-functions.php. Is there any other file which affects the change? Thanks in advance.. Daniels.
