BHi All,
I am new to excel, so any help would be great :)
I want to automatically insert a set text string for instance, ABC into
A1
only if there is a number inserted into cell B1 for instance 12345.
So if I insert 12345 into cell B1, A1 would then show ABC, if I insert
6789
into B2, A2 would then again return ABC.
However if there is no value in B1 or B2 then I need A1 and A2 to be blank
and not return N/A# etc
