i have a xlsx doc that will not let me enter or change some cells and I have not been able to figure out what the problem is, the doc or sheet is not protected in any way.
when I copy and past from another line it does so correctly but then I can not change any of the fields and it reverts back to the copied entry
if I try a blank cell the entry does not take at all.
Can anyone point me in the right direction on how to fix this please
