THANKS, that's exactly what i need, but 2 questions remain:
1) Each cell that has a comment box has a red flag in the corner, showing that it has a comment box attached. Is it possible to NOT have this flag (or not show it). If not, how about changing the properties of the flag so that it's white, and therefore won't be seen as it will blend in with the background of the cell itself?
2) In the comment box i want to show a date, which comes from a variable in a CSV file. Therefore the date is in 'regular' number form (ie- 37466 instead of 07/29/02). What is the code to have this appear in date form within the text box? I tried something like variablename.NumberFormate=mm/dd/yy but it didn't work. Is it possible to change the format within the text box, or is it necessary to change the format on the CSV file before i start using it within the text box.
Thanks again for your answers. I was going down the wrong path, trying to learn about mouse rollover effects (which require Java which i know NOTHING about) and this is MUCH easier, assuming i can fix the above two situations.
