nanmean and mean ( 'omitnan') error

Hi all,

I have a question, I have a data set like this

I replace empty cells with nan and then I try to use nanmean and also mean (PAR_1, 'omitnan'), but I face this error anyway:

Error using sum

Invalid data type. First argument must be numeric or logical.

Does anybody know how can I solve this?

Thanks,
