Non-zero cells returning zero

[hhravn]

For some reason i cannot chart the data from this excel sheet. I have
a function retrieving data from the web, and returning it to the
cells, and the values display correctly, but when i try to chart it,
the value of every cell is displayed as zero. Any ideas as to what the
problem could be?

Ok, i've got it.. The function returned a string.. Changing it to int
solved the problem. I'm new at excel )
