Excel Help on Creating an Email When Any Cell in Excel Has Been Changed

Hi there

I am a total beginner but I have been trialing macros and VBAs for the past few weeks and probably still none the wiser!!

I am trying to set up an holiday card on excel which I have the template for but I need an email sent to me, the manager, each time it is updated by my staff requesting Annual Leave. Each member of staff will have a program each.

Please could anyone help me with a formula? a code?

thanks in anticipation
