Formula to find if two conditions are true, cells only need to contain not be equal to exactly

[suprsnipes]

Is it possible to use a formula that can find if multiple conditions are true for the following;

1. B11 contains the letter "O" and,
2. G11 contains a value greater than or equal to 57

=and(isnumber(search("o",b11)),g11>=57)

 

[Sektor]

=IF(AND(NOT(ISERROR(FIND("O",B11))),G11>57),"OK","Not OK")
