Problem with Arduino LCD

Hi
can anyone tell me why my adruino LCD displays either "wwwwww" or "ffffff" when I run my program? if I run the examples in the Arduino its working just fine, but once I run my code it gives me either "wwwwww" or "ffffff"

Yes

What Larry is saying in his own way it:

click the MODIFY button in the upper right of the post window.
Highlight all you code.
click the "#" CODE TAGS button on the toolbar above just to the left of the QUOTE button.
click SAVE (at the bottom).
When you post code on the forum, please make a habit of using the code tags "#" button.
