In this tutorial we are going to use the IF and SUMPRODUCT functions to determine if a series of courses or requirements have been completed for a student or employee. We will also use Conditional Formatting to make the results more visual.

Here I have a list of employees or students and I need to determine if each has completed the three courses they are required to finish:

I’ve also created a Data Validation drop down list of all the individuals in cell B2:

The formula we are going to use in cell B3 is:

**=IF(SUMPRODUCT(($B$6:$B$26=B2)*($C$6:$C$26=”Yes”))=3,”Complete”,”Not Complete”)**

It is a basic IF statement that says if the result of the SUMPRODUCT function is 3, then enter “Complete”, if not then “Not Complete”. So the key to this formula is the SUMPRODUCT function:

**SUMPRODUCT(($B$6:$B$26=B2)*($C$6:$C$26=”Yes”))=3**

How SUMPRODUCT works is it takes the SUM of the PRODUCT of two or more sets of variables. In our case our two sets are:

**$B$6:$B$26=B2** – this takes the name in cell B2 and compares it to the list of names in column B.

**$C$6:$C$26=”Yes”** – this takes the Yes or No answers in column C to determine if they are “Yes”.

The result of the first variable shows a TRUE when the name matches cell B2 and is:

{FALSE;FALSE;FALSE;TRUE;TRUE;TRUE;FALSE;FALSE;FALSE;FALSE;FALSE;FALSE;FALSE;FALSE;FALSE;FALSE;FALSE;FALSE;FALSE;FALSE:FALSE}

The result of the second shows when the entry in column C equals “Yes” and is:

{FALSE;FALSE;FALSE;TRUE;TRUE;TRUE;TRUE;TRUE;FALSE;FALSE;FALSE;FALSE;TRUE;TRUE;TRUE;TRUE;TRUE;FALSE;TRUE;FALSE;FALSE}

So when you convert those so FALSE = 0 and TURE = 1, you get:

{0;0;0;1;1;1;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0} * {0;0;0;1;1;1;1;1;0;0;0;0;1;1;1;1;1;0;1;0;0}

Which results in:

{0;0;0;1;1;1;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0} = 3

Therefore, there are only three positions in the two sets of results where they are both a 1. And 1 x 1 =1. All the other combinations produce a 0, and the sum of those three 1’s is 3. Any other combination will not equal a 3. So when I choose a person that has completed all three elements, the formula in cell B3 shows “Complete”:

An alternative to this method is to enter into column F the following formula:

**=IF(SUMPRODUCT(($B$6:$B$26=B6)*($C$6:$C$26=”Yes”))=3,”Complete”,”Not Complete”)**

The only difference is that instead of comparing to cell B2, we are comparing each line to the name in the same row in column B. Now when we copy it down, we get the following:

Now I’ll add Conditional Formatting to the cells with the following formula:

After I set the formatting style I want, here is the result:

Anywhere that “Complete” is in all three rows for the same person, the formatting is activated.
