Conditional Formatting based on a positive number in a cell

I am trying to create a conditional formatting based on another cell having a positive number.

If cell C16 is a positive number, then cells A16 & B16 will fill/shade with a color.

I am not sure if this needs to be done with a formula or if there is another way.

Thanks for any help.

Select A16:B16 and add conditional format, Use a Formula to determine which cells to format.

Use this formula, assuming you count zero as positive.

=$C16>=0
