Change the background color of an individual cell in a form/subform

To conditionally set the background color for a cell based on values, put something like the following in the On Draw event for the cell:

If(population > 1000000)
{
	RGBColor(City, 0, 0, 0, 255, 0, 0)
}
Else
{
	RGBColor(City, 0, 0, 0, 255, 255, 255)
}
