Merge 2 formulas require ASAP

Can someone help me merge the two formulas together please and I also need it to work out the following way

So basically

If A2 = Monthly & B2 = Active.... do the following (If B2 says anything other than Active it must not return a value or can return 0)
=IF(H2<20.99,H2*12.5%,IF(H2<30.49,Sheet2!$D$4+((H2-Sheet2!$D$3)*12.5%),IF(H2<39.59,Sheet2!$F$4+((H2-Sheet2!$F$3)*12.5%),IF(H2>=39.59,Sheet2!$H$4+((H2-Sheet2!$H$3)*12.5%),0))))

If A2 = Yearly & B2 = Active.. do the following (If B2 says anything other than Active it must not return a value or can return 0)
=IF(H2<149.99,H2*2.5%,IF(H2<299.99,Sheet2!$E$4+((H2-Sheet2!$E$3)*2.5%),IF(H2<399.99,Sheet2!$E$4+((H2-Sheet2!$E$3)*2.5%),IF(H2>=399.99,Sheet2!$E$4+((H2-Sheet2!$E$3)*2.5%),0))))

I need to merge the following formula together and paste it into K2
