crazy loop behavior...I must be doing something wrong here

I am currently experiencing a strange problem with a loop.

The code I have written does this

It takes a list of files [S r1].
It gets the file size for the file represented by each element of the list
It adds up the file sizes for all the files in the list to get a total number of bites as a float (I treat all numbers as floats because at first I was using itof and ftoi and thought that this was the cause of the problem)

while the packages are loading, the code keeps track of how much in bytes have been loaded with the packages, and how much a percentage of the total has been loaded.

For some reason, the percentage figure jumps from 35% to 222% when a package that is only 1% of the total amount of bytes is loaded.

I've tried to figure out why, but have failed?  It's a bug (probably not) or I'm doing something wrong (probably)

code to get size of all files loaded together.  everything is properly indented in bluefish, but it gets messed up when pasted into crhome or openoffice, so I made the indents more readable by hand. (they are properly nested in bluefish)

ack! what am I missing (after looking again and again)
thx for your help

//filelist is [S r1], totalfilesize is F
fun getsizeofallfilesaddedtogether (filelist, totalfilesize)=
	//get head of list
	let hd filelist -> filepath in
	let _checkpack filepath -> file in 
	(
	if filelist == nil then
	//open then brace
			(
			totalfilesize;
			)
			else
			(	
			set totalfilesize = totalfilesize +.  itof((_fileSize file));
			set filelist = tl filelist;
			getsizeofallfilesaddedtogether filelist totalfilesize;
			);
	);;

code to print out status of file loading, giving name of file, size of file, and percentage of total bytes loaded:

  
 typeof total_filesize = I;;
 typeof linecount = I;; 
 typeof bytesloadedsofar = I;;
 typeof fbytesloadedsofar = F;;
 typeof loadedfilelist = [S r1];;


fun loadOS3D (file, projname, pw, ph, fullscreen, text_control,  log_window,  environment)=
  set total_filesize = 0;

Re: crazy loop behavior...I must be doing something wrong here

and even after all that indentation cleanup, chrome manages to make things less readable ....sigh

Re: crazy loop behavior...I must be doing something wrong here

[solved]

I was making the list of files smaller and smaller, which made the percentage get bigger and bigger. hmm time to get rid of those annoying floats and see what happens.

Re: crazy loop behavior...I must be doing something wrong here

final code that works...i've given up on copying and pasting indentations because every method I have tried fails...if any of you guys has a method of doing it please tell me so I can save your eyes. it would be great if the forum allowed file attachements, fwiw (just for small files such as .pkg files)
