Can you please help me understand what to put in all of the IFS logical test and value boxes (all of them for all steps)? I understand how to do the first couple based on the photo example included, but unsure about the rest. Thank you!

Create an IFS function to display a response rating. Note: If your version of Excel does not include the IFS function, build the following nested IF function =F(C7/B7>=20%,$C$15,F(C7/B7>=15%,$C$16,F(C7/B7>=11%,$C$17,$C$18))) to display the rating a. Click cell D7. The response rate and ratings are shown in rows 14:18. b. Start an IFS function and select C7 for the Logical_test1 argument. Type / for division and select cell B7. Type >=20% to complete the test. c. Click the Value_if_true1 box, select C15, and press F4 (FN+F4) (Figure 6-107). Figure 6-107 First_Logical_test and Value_if_true arguments d. Click the Logical_test2 box, select C7, type I, select cell BZ, and type >=15%. e. Click the Value_if_true2 box, click cell C16, and press F4(FN+F4). f. Complete the third and fourth logical tests and Value_if true arguments (Figure 6-108). a. Copy the formula in cell D to cells D:D10
