Error Problem with crontab running a script

I am trying to use the CRON utility in Fedora 11 & CentOS...

I intend to run a script which pops up a warning message every hour and i made the following entry using "CRONTAB -e "

Code:
* * * * *  sh /bin/myscript.sh

But this does not seem to be running.

Another thing to note is that, My script contains a GUI command
" dialog --title or in my case whiptail --title "

I was wondering if CRON runs this scripts, will show a pop up...?

Can this script be run using CRONTAB..?

Please help

That will run the script every minute, not every hour.

To run the script on the hour:
Code:
0 * * * *  sh /bin/myscript.sh

You need to set the DISPLAY variable.

How do you Declare a Display variable within a script....

These are commands which output the contents inside the declaration

It's DISPLAY, not Display.

Code:
DISPLAY=:0.0

(Check the value in a shell first.)
