Please can someone tell me what's wrong in this code

Question

1var a=0;
2function main(){
3var inFolder = Folder.selectDialog("Please select folder to process");
4//Save the Current Preferences
5var startRulerUnits = preferences.rulerUnits;
6preferences.rulerUnits = Units.PIXELS;
7//Get all the files in the folder
8var filelist=inFolder.getFiles()
9n=filelist.length;
10//Open each file
11for(a=0; a<n; a++){
12// The fileList is folders and files so open only files
13if (fileList[a] instanceof File) {
14open(fileList[i])
15var docName = app.activeDocument.name;
16app.activeDocument.flatten();
17activedocument.save();
18}
19}
20}
21main();
Says the error is "filelist is not recognized".    on line 14.   I thought I had fully defined 'filelist' on line8
I thought filelist was a one-D array variable.

Answer 1

Also, in lines 8 and 9 you use a variable called "filelist" but in lines 13 and 14 you call it "fileList" (notice the capital-L).
JavaScript is case-sensitive, so you must be consistent with your variable names throughout.
