Finding correct points problem...

[fomur]

Hi,

I am developing maps using chartFX extensions. Basically, I have one US map and one ZoomedState map. Whenever a state is clicked at US map, ZoomedState map loads clicked state on the USmap. I want to paint some states with different colors and I can do that by using the following sample code.

tempRegion = USMap.FindMapRegion("CA");USChart.Points[tempRegion.Point].Color = Color.PaleGoldenrod; 

However, when I want to do same thing with ZoomedState map it does not work. I am using 3-Zip code maps for showing ZoomedState map and want to paint specific ZIP regions with a different color. So when I use following code after NY 3-Zip code loaded to ZoomedState map it does not change color.

tempRegion = CountyMap.FindMapRegion("127");countyChart.Points[tempRegion.Point].Color = Color.PaleGoldenrod;

When I debug my code, I have seen that when first code  is executed it returns correct point code for California which is 3. However, when I execute the second code it returns -1 as a point value for 127 zip code. Can you help me out that where am I doing a mistake? Thanks...
