Hi, please help me with this

1) check if D6/100 1,5

2) if 1 true: check if D6/100 < 25

3) if 2 false: check D6/2501,5

4) if 3 true: check D6/250<25

5) if 4 false check D6/500 1,5

6) if 1 false: then B30= "can't use"

7) if 2 true: B16 = 100

8) B30 =(B16*60/((B2*F2)/(1*F2)))

9) If 4 true: B16 = 250

10) B30 =(B16*60/((B2*F2)/(1*F2))

11) If 5 true: B16=500

12) B30 =(B16*60/((B2*F2)/(1*F2))



Any help we´ll be appreciated
