# Overview

You will need to build your **Conditional Expressions **to define your **Threshold Criteria.**

In your **Conditional Expressions, **you can use the following mathematic conditions:

**Less than (<)****Greater than (>)****Equal (=)****Less than or equal (<=)****Greater than or equal (>=)****Not equal (<>)**

**IMPORTANT: **When writing your Expressions, use the symbols referenced above in the parentheses and not the actual word. For example:

**Do not**write "A is less than 4"**Do**write "A<4"

You can also include **conjunctions **in your expressions to combine more than one condition using the following **conjunctions:**

**AND****OR**

# Four Conditional Expression Examples

For a simple **Conditional Expression **in which the tester only makes use of the **Greater than **condition, refer to the following example in which the conditions are as follows:

- The
**percentage of Project defects open (D)**is - the
**percentage of Project defects closed (B)**.

To do so, the tester created a simple **Conditional Expression, **following these steps:

- In the "Conditional Formatting" dialog, note your selected
**Status Fields**and their accompanying upper-case letters.**IMPORTANT:**When writing your**Expressions,**use only the associated upper-case letter to represent your status field(s). - In the "Conditional Expression" text-field, type your
**Conditional Expression.**To highlight a portfolio in which the percentage of**Project Defects Solved**is**Greater Than**the**Percentage of Defects Yet to be Solved**, write one of these two expressions:- D>B
- B<D

- Select
**Update,**and the conditional formatting will save. - Continue the process above to include more conditional formatting.
- Select
**Save**at the top of the Portfolios page to save your changes to the**individual****portfolio you have selected**.

If you want to create different **Conditional Expressions, **follow the same steps as above using different **conditions**. Below is an example of a more complex **Conditional Expression **that defines a **Threshold Criteria **based on the following conditions:

- The
**number of****Test Runs Blocked**is**less than four****AND** - The
**percentage of Test Runs Failed**is**less than three**

AND - The
**percentage of Test Runs Blocked**is**less than four**

So far, each conditional expression has relied upon the conditions **Greater than (>) **and/or **Less than (<). **However, users can also use **Greater than or ****Equal to (=) **in their **Co****nditional Expressions. **Refer to the example below in which the conditions are as follows:

- The
**number of Defects Open**is either**Greater than**or**Equal**to**two**

AND - The
**n****umber of Defects Closed**is**Greater than**or**equal**to**one**

Below is one more example in which a tester defined a **Threshold Criteria **with the following conditions:

- The
**p****ercentage of Test Runs Incomplete**is**Not Equal to Zero**

AND - the
**n****umber of Test Runs Closed**is**Less than One.**
