Column ‘usable_period_H' is NA for 12,114 records #7

Why NA exists?
For these records, how do I obtain the lowest usable period?

This column was updated. Lowest_Usable_Freq_H1 = HP_H1_1.25 Lowest_Usable_Freq_H2 = HP_H2_1.25 Lowest_Usable_Freq_Ave = max(Lowest_Usable_Freq_H1, Lowest_Usable_Freq_H2) usable_period_H = 1/Lowest_Usable_Freq_Ave
