I am having an issue with NOW() .
Unfortunately for you, NOW() means "now"; it may be that you need a
THEN() function!
I am using =IF(ISBLANK(A3),"", IF( ISNUMBER(B3), B3, NOW() ) )
I have copied this by dragging the corner of the cell to 100 other
cells the problem is when i enter data into a cell in column 3 ...
Er, column A, perhaps?
... the time changes in every cell in column 3 and it should not.
You clearly don't want it to, but since NOW() means "now", it should.
By default, each time you make changes to a spreadsheet, formulae are
recalculated, and since all your formulae contain a reference to
NOW(), that will be updated to the current date and time, not the one
at which previous changes were made.
it does not in another sheet that is using exactly the same formula.
One possibility is that you have AutoCalculate toggled off there, but
that will prevent *any* changes, so the original date and time will
not be inserted where you require it. You can use Recalculate to
cause new changes to happen, but - once again - that will affect all
parts of your spreadsheet and so change all the dates and times.
One workaround is, each time you make an entry and create a new date
and time, to copy the cell contents and paste them back, but using
Edit | Paste Special... (or Ctrl+Shift+V, or right-click | Paste
Special...) instead of ordinary Paste. In the Paste Spacial dialogue,
ensure "Paste all" is not ticked and "Formulae" is not ticked. This
will remove the formula and freeze the contents of that cell. But
note that any later changes to the corresponding data cell will no
longer change the date and time in that cell.
I trust this helps.
