creating a reset button for selected cells

[MR64]

I am new here and have a little exp with xls2003 and there is probably a simple way to do this, but after looking through FAQ's couldn't find exactly what I needed.

Have a simple worksheet that i use for bidding jobs and i just want to add a reset button at the top to clear all the cells that i have entered quantities for specific material items.

I did a macro, but I didn't like the way it 'jerked' around the page mimmicking every page movement that I made selecting the cells that needed to be reset. Currently do not have any cells locked (like the type of material, price, etc).

Thanks in advance,

Mark
