Problem opening xlsx file

I’m testing with xlsx files --> but when opening the attached file the follwoing error occurred: Invalid formula:"=SUM(X6:Y6) + Z5

Is there anything wrong with my document? but when opening with office 2007 there is no problem with this formula.

Thanks for help.


Thanks for the template .xlsx file.

We will figure it out this formula issue for .xlsx file soon.

Thank you.


Please try this fix. It's caused by shared formula.

It works now.
