Depending on the value in other cells, the result can be a time or an
empty string (""). In this case, E9 is an empty string, so E10 becomes
”#VALUE!”, and in fact every cell below E10 is also ”#VALUE!” because
of this.

Can you provide an example file? This used to be a problem but it is fixed
in 3.4.4 (at least under Windows)
I could, but it's not needed, I think. I just did this simple test in
3.3.4 and 3.4.4:

Open LibreOffice Calc from scratch.

A1:
=""

A2:
=A1+1

In LibreOffice 3.3.4 (Ubuntu 10.10), A2 displays:
1

In 3.4.4 (Ubuntu 11.10), OOO340m1 (Build:402), A2 displays:
#VALUE!
Try in A1 no data/empty cell and in A2 =A1+1, you will get 1 in A2. You are adding a text and number and the + operator is not used for concatenation.

This has to do with operator overloading, are other, similar, operations allowed when using '+'. Some may allow it and others may not, restricting its use to mathematical operations only. LO uses the '&' operator for concatenation.

If you use A1 = "" and A2 = A1 & 1 you get 1.


Kind regards
