Error on saving new version of workbook

[Johnny C]

Hi

Each time I save a quite complex model as a new version, I get this error:

The reference is not valid. references for titles, values, sizes, or data labels must be a single cell, row, or column

It doesn't appear when I save the file normally (overwrite previous).

it appears to relate to charts, the model has a lot of them. Some of them use 2 row column headers which has the effect of forcing the 2nd row to wrap regardless of the length of the text in the first row. is that what's throwing the error?

I've run Document Inspector and it sheds no light on the error.

try merging the 2 header cells ?
