Add date/time stamp to comment when cell is marked "X"

Hello excelforum.

Hopefully my request for help is relatively simple for your expertise, but it is beyond my scope.

I have a range of cells...say A1 to D10 all with column headings

What I would like to do within that entire range is this;

Say I place an "X" in A1...I would like to automatically generate a comment in that cell with my Name and a Date/Time stamp. This would indicate that a particular task has been completed.

Then the same to occur when I place an "X" in...lets say B3..and so on within the entire field.

Nothing fancy...standard comment box...but with Tahoma 12 font bold and with auto resize to suit.

Many thanks in advance.
From desperately needed.

Hi Keebellah

If a mistake is made the comment can be deleted manually...not that critical.

Unfortunately it has to be able to run across several versions from 2003.

Thank you for your assistance.

Hi Keebellah

That's brilliant...works great.

I'm no expert in these things...so please forgive my ignorance.

I assume I just paste that code into my worksheet and change the range to suit?

Absolutely amazing...did you just write that?...uncanny

Thank you so much...

Hi Keebellah

Just a little insight if possible.

Worked great on your demo sheet...when i pasted code into my sheet and changed the range to suit my data...date stamp worked great.

But when "X" was removed the comment remained...no big deal...as I said it can be done manually if an error is made.

Only wondering why it would do that? As I said...I am completely bamboozeled by code.

Again...thank you so much...

Keebelah...thank you...all good.

As with all things of this nature...which is completely out of my league...

A larger font size would be nice...i find Tahoma 9 way to small for my weary eyes...Tahoma 12 would be nice...what and where would I be able to insert that.
I tried..in my rock cracking style...but failed miserably I'm afraid.

Any suggestions...better still answers.

Code worked great when I put in the $ signs in the range...

Again...thank you.

Thank you so much...you have been most kind and most patient.
