[SOLVED] Always outputting same image... not desired

[deadlyp99]

What this code is designed to do, is to seperate my map, and use different images based on population.

Currently, it is outputting the same image every time "images/mapsquares/d00.gif".

 

Does a for loop only call the function one time and use the result every time, or is there an error in my code I cannot find? Also, will converting "GetCitySquareIcon" to a class rather then a function help at all? Because other parts of my code are not producing this error from what I've seen.

 

Thanks for any replies

 

<?php
		function GetCitySquareIcon($CityID, $OasisType, $CityPoP, $Relation)
		{
			$MapDIR = "images/mapsquares/";
			$Type = ".gif";
			$MapTypeImages = array('d00','d01','d02','d03','d04','d05','d10','d11','d12','d13','d14','d15','d20','d21','d22','d23','d24','d25','d30','d31','d32','d33','d35');
			$BlankMapImages = array('t0','t1','t2','t3','t4','t5','t6','t7','t8','t9');
			$OasisTypeImages = array('o1','o2','o3','o4','o5','o6','o7','o8','o9','o10','o11','o12','o99');

			if ($CityID >= 1)
			{
				if ($CityPop < 100)
				{
					return $MapDIR.$MapTypeImages[0].$Type;
				}
				elseif (($CityPoP > 100) && ($CityPoP < 250))
				{
					return $MapDIR.$MapTypeImages[6].$Type;
				}
				elseif (($CityPoP > 250) && ($CityPoP < 500))
				{
					return $MapDIR.$MapTypeImages[12].$Type;
				}
				elseif ($CityPoP > 500)
				{
					return $MapDIR.$MapTypeImages[18].$Type;
				}
			}
}


			for ($Y = $StartY; $Y >= $EndY; $Y--)
			{	
				echo "<div id=\"row".$Y."\">";
				array_push($Yarray, $Y);
				for ($X = $StartX; $X <= $EndX; $X++)
				{
					echo "<div class=\"". $CssClass.$CssClassNum."\" alt=\"".$X.",".$Y."\"  style=\"z-index:5;width:74px;height:74px;background:url('".GetCitySquareIcon($CID, $OType, $Pop, 0)."');\"></div>\n";
					array_push($Xarray, $X);
					$CssClassNum++;	
				}
				echo "</div><br />";
