updating time once only when a cell is filled

[Vic]

Hi, Excuse my lack of experience with excel, I tried to get an answer
googling for this problem I have, but I didn't succeed yet solving
it.

I'm trying to fill a form using excel, but I want that whenever a cell
is filled, the time it was filled is updated. The problem I find is
that time is updated in all the cells whenever a cell is change, do I
make myself clear?, imagine I have these table:

A B
1 +if(a1="","",now())
2 +if(a2="","",now())


So initially I have:

A B
1
2

when I enter something in A1, I get

A B
1 123 15:23:20
2


Then later when I enter something in A2, I get

A B
1 123 15:25:30
2 345 15:25:30

when what I really need is:

A B
1 123 15:23:20
2 345 15:25:30

so... any idea about how can I get it done?

Thanks a lot. Have a nice day

Vic

You need keyboard shortcut, VBA or circular referencing
