Sharing Excel

[scal]

Hi, I have a shared workbook, which is set up from a template made by
someone else. I made some changes to the workbook, saved as a
template, and whenever I put a the new workbook into the system
something is different.
Previously, when other users were using at the same time, if someone
started using a row, Excel would automatically place them on the next
available row. But now when someone uses a new row, Excel doesn't
recognise that someone else may have used a new row.
I have tried checking the Advanced options to save often, but it has
made no difference. Does anyone know about this type of sharing?

thanks in advance
Sue
