I ended up transfering the file contents (which was in a single column array) to the Subscripts in the assignment.... that worked too. Thanks again.

What you should always do is verify that data coming in, especially from something such as a file, is in the format you are expecting. For example: Dim strLine As String = sreStreamReader.ReadLine() If IsNumeric(strLine) Then intStudentScore(19) = Convert.ToInt32 (sreStreamReader.ReadLine()) Else MsgBox "Line 20 is not numeric" ' Throw exception or exit here. End IF Hope that helps Tue, 22 Nov 2005 17:55:58 GMT http://dotnutz.tribe.net/thread/91fd9477-4b51-456d-b3e9-d65d63c0938a#e2c875fc-d1f1-428e-bce7-794056d80c7f Psychotty 2005-11-22T17:55:58Z http://dotnutz.tribe.net/thread/91fd9477-4b51-456d-b3e9-d65d63c0938a#d03189ec-af38-437d-8a4b-9be26472f781 what does the file look like that you're reading? Also -- if you delete the windows-form-generated code, the code snippets you post will be a slot shorter.

I have to search a txt file with 20 array elemnts in it called "scores.txt" in the Bin folder, then list a count of all number of students who got that grade. the line in my code that debug is stopping on is intStudentScore(19) = Convert.ToInt32(sreStreamReader.ReadLine()) what is wrong with this assignment statement or why won't this program work. When I type 72 in the input text, I should see the number 3, because that's how many students got a 72. Help here's my code: 'Project name: Scores Project 'Project purpose: The project displays the number of students earning ' a specific score.
