Hi, I've just written a sort method for my top ten songs chart program, which just hold a list of the top ten songs.

Each records is made up off the following fields:

Chart Position :int
Song Title :string
Song Artist :string
Record Company :string
Price :double

The method sorts records by Chart Position fine, but when I try to sort by Song Artist and re compile it gives me a error like the following error:

"cannot apply > to string" or somthing.

How can I compaire the strings to see which is greater, I want to sort Song Artist alphabeticly.
Here is how I'm sorting by Chart Position (I'm using bubble sort as you cannot have more than 10 records).

Code:
passes = 1;
			swap = true;
			
			while ( ( passes <= arrayToSort.length - 1 ) && ( swap = true ) )
			{
			    i = 0;
			    swap = false;

			    while ( i <= arrayToSort.length - 2 )
			    {
			        if ( arrayToSort[i].chartPosistion > arrayToSort[i + 1].chartPosistion )
			        {
				    tempRecord.chartPosistion = arrayToSort[i].chartPosistion;
				    tempRecord.songTitle = arrayToSort[i].songTitle;
				    tempRecord.songArtist = arrayToSort[i].songArtist;
				    tempRecord.recordCompany = arrayToSort[i].recordCompany;
				    tempRecord.price = arrayToSort[i].price;

				    arrayToSort[i].chartPosistion = arrayToSort[i + 1].chartPosistion;
				    arrayToSort[i].songTitle = arrayToSort[i + 1].songTitle;
				    arrayToSort[i].songArtist = arrayToSort[i + 1].songArtist;
				    arrayToSort[i].recordCompany = arrayToSort[i + 1].recordCompany;
				    arrayToSort[i].price = arrayToSort[i + 1].price;

				    arrayToSort[i + 1].chartPosistion = tempRecord.chartPosistion;
				    arrayToSort[i + 1].songTitle = tempRecord.songTitle;
				    arrayToSort[i + 1].songArtist = tempRecord.songArtist;
				    arrayToSort[i + 1].recordCompany = tempRecord.recordCompany;
				    arrayToSort[i + 1].price = tempRecord.price;
				    
				    swap = true;
			        }
			        
			        i = i + 1;
			    }
			    
			    passes = passes + 1;
			}
To sort by Song Artist

I did the same as above but changing the if from:

Code:
if ( arrayToSort[i].chartPosistion > arrayToSort[i + 1].chartPosistion )
to:

Code:
if ( arrayToSort[i].songArtist > arrayToSort[i + 1].songArtist )
