not running any scripts

Hi,
I am running fedora core 2 on a Dell Inspiron 5150. I have acpi installed as my kernel version is 2.6.10
I have written scripts and events in /etc/acpi/events but none of them get executed
the state files in /proc/acpi/button does change when i close my lid etc.
but the scripts are not executed.
Also, I am not able to put my computer in stand-by mode even manually.

I also tried rebuilding kernel with all acpi support. but no use.
can anyone guide me on this
