Error with CUDA_Occupancy_calculator macro in LibreOffice

Hi,

I downloaded latest CUDA_Occupancy_calculator and now whenn I try to use with LibreOffice on Linux I have the following macro execution error:
BASIC runtime error.
‘1’
Type: com.sun.star.container.NoSuchElementException
Message:
on line 24 Set current_chart = ActiveSheet.ChartObjects(“Chart Register Count”).Chart
of Sub updateAxes()

Is CUDA_occupancy_calculator.xls file supposed to work with LibreOffice ?
Which tools are used by Linux users to open it ?
Up to now I never had this issue with CUDA occupancy calculator

Thanks by advance
Julien
