Hello Edward,
Thank you for your help.
I'm getting Syntax error with The code.Also Variable firsbarofday
used without having been initialized.
Could you please upload the right one or send it to my yahoo ID.
Again thank you very much.
Regards,

in the chart as a dark grey background (see inserted chart). You will
need to adjust:
