error when calculate p value for subset or xsec A-A'

[GEOSCIENCELXG]

I tried to use the "estimate P" under f(t) function to estimate p c k parameters of the Omori-Utsu law, but it is shown with the below error, how to solve it?

Incorrect number or types of inputs or outputs for function
'mypval2m'.
