Conditional formatting help

Hi Fusilier2 , You're encountering the error because of a mismatch between data type and rule configuration.

Why You're Getting the Error:

• Your measure returns numeric values (like -3, 0, 4), not percentages.
• But in your conditional formatting rules, you're using "Percent", which expects values between 0 and 1 (i.e., 0%–100%).
• So value < 0 (Percent) is invalid, causing the red icon rule to error out.

How Fixing to "Number" Helps:

By changing each dropdown to "Number":

• Power BI will compare your measure against actual numbers like 0 and Max.
• The logic value < 0, = 0, and > 0 will work as expected.

Set up the icon rules like this:

• Red icon: If value < 0 → Number
• Yellow icon: If value = 0 → Number
• Green icon: If value > 0 → Number

This configuration will correctly apply icons to your Headcount Excl Casuals month on month measure based on the direction of change.
