# Modify Macro to Perform Additonal Backwards-Functionality

Experts, I would request your assistance in modifying the attached macro to performing the following functions:

## 1.

I would like that if an end-user were to make an entry into daily, monthly, or annual, the value in Cell D25 be the result of Cell D20 multiplied by D25
For example, I entered a daily value of 50, into Daily the current Macro Calculates D25 to equal "18,250". Then D26 is 18,250xD20=47,450

## 2.

I would like that if an end-user first made an entry into either daily, monthly, or annual saw the result of flight hours as describe by Step 1, BUT then decided he would like to use Annual flight hours as his primary input, as a result, D23:D25 now must adjust based on the new flight hour input divided by D20 and the appropriate frequency either 365days or 12 months
For example, I entered a daily value of 50 into Daily the current Macro Calculates D25 to equal "18250". Then D26 is 18,250xD20=47,450. However, I decide that 47,450 is not what I really would like for annual flight hours to be and manually enter in 50,000 instead. There by changing D23 to (50,000/D19); D24 to (50,000/D19)*30.4 [average number of days in a month]; and D25 to (50,000/D19)*365.

There by changing D23 to (50,000/D19);

D19 is blank. Did you mean D18 or D20?

Seems to work just fine, quick question though:

Why under the Cases did you only modify "monthly" with
``````Range("D26").Value = Range("D20").Value * Range("D25")
``````

I've noticed a bug during testing too.

If you simply go to select a frequency first rather than inputting a daily, monthly, or annual amount then Flight Hours remains blank after your selection.

That line was added to get you the value in cell D26 - Annual Flight Hours. As for the "Bug", that value was not addressed in case \$D\$22. This will correct that error:

Gotcha, Thanks, I have a better understanding of the macro now too and I wrote a case for "Annual Flight Hours".

`````` Case "Annual Flight Hours"
Range("D23").Value = Round(dblAnnual / 365, 0)
Range("D24").Value = Round(dblAnnual / 12, 0)
Range("D25").Value = dblAnnual
Range("D26").Value = Round(Range("D20").Value * Range("D25"), 0)
``````
