Contour tool failure

Hello everyone,

the contour tool for grasshopper fails to read. The data is being read from a excel file using the ‘read excel’ the fail reads as follows:
‘data fonversion failed from text to number’

any ideas as to why this has happened? perhaps it is trying to read text within the excel as a meaningful floor?

Thanks,

Kim
