1) Write an IF function for cell H3 that assigns the value of cell A7 to cell H3 if the value in J7 is less than the value in cell Q2; otherwise have the IF function assign zero (0) to cell H3.
It should be something like this:
In H3, type =IF(J7
2) Write an IF function for cell P8 that assigns the text, "OK" if the value in cell S3 is five times greater than the value in cell Q2; otherwise, have the IF function assign the text, "Not OK" to cell P8.
In P8, type =IF(S3=(5*Q2),"OK","Not OK")

I did not check if the formulas work. You can look in the Excel Help for explanation about the IF function and conditional formulas.
