Help with Conditional Formatting in Power BI

Hello everyone,

I have a table in Power BI from data pulled from an Excel spreadsheet, consisting of the following columns:
-"Item" : The product or item name
- "OnHand" : Value of how much of the item we have in stock
- "NOV-23" : Usage forecast for Nov-23
- "DEC-23" : Usage forecast for Dec-23
- "JAN-24" : Usage forecast for Jan-24
- "FEB-24" : Usage forecast for Feb-24
- "MAR-24" : Usage forecast for Mar-24

The month columns display negative values indicating how much stock of an item will be used for that particular month. For example, if the "OnHand" value is 100 and in December-23 we will be using -30, the corresponding cell would be green in background color, indicating we would still be covered (as 70 would be left), but if in Jan-24 we required -80, we'd be in the negative and the corresponding cell should be red in background color. I want to apply this conditional formatting in Power BI but can't get the DAX code to work at all. Any help or input would be greatly appreciated.
