Help with my program

I'm trying to collect the following data to be written to a file:

total conversions by type for each user
total conversion for each user
total conversion by type for all users
total conversion for all user.

I think theres something wrong with my code because when it writes to the file it gives a -895674. can anyone help me
Heres my file:

Code:

>> fprintf(otpt, "%d", Tcount);

You are printing Tcount to the file, yet it hasn't been initialized.

I think what you meant to do was this :

Code:

---

Tcount = totalCount(count1, count2, count3, count4, count5, count6);

---

[EDIT]
I just noticed that none of the other variables have been initialized as well, so totalCount() will always return garbage.
[/EDIT]

I was able to figure out how to collect the data for Total conversions by type for each user and total conversions for each user. But i can't figure out how to get the total conversion by type for all users and total conversion for all users. can anyone help me.
