I currently have a excell file that has multiple worksheets. I would like
to
add a worksheet that would allow for data entry. Once the data is entered
into this first page, i would like it to automatically fill in the same
information into the other worksheets. ie customers name would be entered
onto the first worksheet and then excell would put the customers name on
all
the other sheets. how can i migrate this data from sheet to sheet?
