I have a feeling it is something simple troubling me, I just cant find out what that problem is. The progam is SO CLOSE! please help me.

that little bit is the problem, I can compile and run, but it only executes the first line of the file and asks for the file again, then does the first line AGAIN and asks for the file AGAIN and so on and so forth repeating untill I terminate the box. If you have any suggestions, me and my friend are having the same problem, thanks for your time,

I was wondering if you coult do the "String Data=inData.readLine(Counter);" to read each line and just bump it up but it said it couldn't resolve the symbol, I pretty much am out of guesses at this point.

What do you want the lines

  1.  
  2. String filage="";
  3. String linetext;
  4.  
  5. BufferedReader inWords=new BufferedReader(new InputStreamReader(System.in));

So filage is actually a line of data from your file.
Now have a look at
Expand|Select|Wrap|Line Numbers
  1.  Data=seekBufferedReaderData(filage);
  2.  
.

And that method takes the fileage and tries to open a file called filage!

sorry, I dont follow. I just want to fill an array with each subscript being a different line of the test values

EX.
1.) 2 3 4 5
2.) 3 6 2 6
3.) 9 2 5 6

i want NumberArray[0]==2 3 4 5 and NumberArray[1]==3 6 2 6, etc etc. I think I can work it out if I can get some direction on that.

Is the data in your file numbered like the example above or is the data just like this

2 3 4 5
3 6 2 6
9 2 5 6
