## Using Formulas to Create Dynamic Custom Values

When you create a Dynamic Custom Value, you can use formulas to create unique calculations/metrics specific to your business or clients. This custom value will display in the Decision Grid and can be used to display, segment, and report on these unique data points.

When entering your formula, you have access to the arithmetic operators listed in the table below. You can utilize standard metrics in Shape, static or dynamic custom values you've created, and/or numbers to create formulas.

- If your formula is valid, a green check box will appear below the formula field and will save when you click
**Create**. - A red warning will appear below the formula field if your formula is invalid. It will not save when you hit
**Create**.

## Using Case Statements to Create Dynamic Custom Values

When you create a dynamic Custom Value, you also have the option to use Case Statements.

Case statements evaluate if a condition is met and return a specific value if it's true. If it's not, it will continue cycling through the conditions until the condition is true and it returns a result. If no conditions are true, it returns the value with the ELSE statement.

### Parts of a Case Statement:

**CASE:** Opens the case statement (required)

**WHEN:** The condition you want to evaluate. You can have multiple WHEN clauses (required)

**THEN:** The result that the Custom Value will return if the WHEN clause is true. A THEN clause must follow every WHEN clause (required)

**ELSE: **The else result is returned if none of the WHEN clauses are true. (required)

**END: **Closes the case statement (required)

### Formatting Case Statements

As part of your case statements, you can use the arithmetic operators above and other operators that check for equality, inequality, or size comparisons.

You can also chain multiple conditions as part of your when clause together. Examples of how these might look are below:

#### Cast Statement 1

CASE

WHEN *condition A* THEN *Result A*

WHEN *condition B* THEN *Result* *B*

WHEN *condition C* THEN *Result **C*

ELSE *Value X*

END

#### Cast Statement 2 (using arithmetic operators)

CASE

WHEN metric 1 = 1000 THEN *Result D*

WHEN *metric 1 != 1000* THEN *Result* E

ELSE *Value X*

END

#### Cast Statement 3 (using mix of all types of operators)

CASE

WHEN metric 1 + metric 2 <1000>THEN *Result F*

WHEN *metric 3 - metric 4 = 1000* THEN *Result* *G*

WHEN *metric 5 OR metric 6 = 5000* THEN *Result **H*

ELSE *Value X*

END</1000>
