How do I make an If-Then formula in Excel?

[kdub1980]

I am trying to make an Excel spreadsheet to calculate my productivity at
work. I would like to make a column that works like this:
If I work X amount of these projects then that's Y% of my goal.
But if I work X amount of these projects then that's Y% of my goal.
At work we have different goals for different "Skill Levels", and you work
all the Skill Levels each day. I would like to be able to put this into a
formula.
I would like to be able to type in, say, 3 (for Skill Level 3) and have that
translate to 3.125% of my goal. And then on the next row I work a Skill
Level 5 which is 2% of my goal. I want to be able to do this by entering in
the Skill Level number, rather than the corresponding percentage. Is this
possible? Thanks for any help you can give me!

Hi

An example:
You enter the skill level into cell A1. When for skill level 1 the
percentage is 5%, sor skill level 2 - 4%, ... , for skill level 5 - 1%, then
you get it by formula
=CHOOSE(A1;5%;4%;3%;2%;1%)

The formula ignores fractional part of number in A1, and returns an error
whenever integral part of number is <1 and >number of percentages in
formula.

Awesome, thank you so much! It worked. It took a little modifying as Excel
only would allow 29 variables and I have 35. But I made a little work around
of putting skill levels 1-15 in one column and 16-35 in another. Also, on
mine, I had to replace the semi-colons with commas, but other than that, the
formula worked!

You can create a separate sheet, p.e. Levels, with a single-column skill
levels table in range A1:A35. I advice to define this table a named range
p.e. SkillLevels
=Levels!$A$1:$A$35
(When you want, you can hide this sheet after that)

Now the formula from my previous posting will look like
=CHOOSE(A1,SkillLevels)
