[keystone]

I have made a change to my home.php title (ie. HELP ZONE) at the top of the page using webmaster mode but now if I go back into webmaster mode to make a modification to the lbl_... of my home.php page it will not allow me to click on it to make the change. The title doesn't turn green anymore and I'm not sure if it is because I added some html to the lbl_ text or not. It works for everyother page as I didn't add any code to those pages. Anyway can some one tell me how to make changes, or where to find the lbl text files?
Thanks
