Problem with fstream

possik (3)
So i have program, which makes a queue with a linked list. the problem is that, when i am inserting the information from the file, the program takes all information , and then makes one more insertion with incorrect data.
here's the code :

		if(delete1==0) glob=glob->next;

}


So the problems occurs in lines 88-96, everything else works normal.

so for example i have file with the following data:

10 B 01010112345 ABBA
15 A 02020213456 U2
16 A 03030314567 4you
17 B 02020213456 ABBA
20 B 04040415678 4you
127 B 04040415678 HipHop2011
1234 A 05050516789 ABBA

the program makes all elem units with this information, and adds another elem with laiks set to 1234, darb set to A, kods and nosauk variables are set to ""

is it the problem with fstream?
