Hello again,
I manage to solve this, so i will post the solution here, maybe someone else will need and use it:
I thought that the problem was that it deleted the rows into the loop, so first we will sum the hour amounts (from duplicate items) at the first item, and at the duplicates will put 0 hours. Then we write the description in the corresponding cell of first item with ";" separator. And after this loop we create another loop for deleting the items with 0 values at the hours column. This is the code and is working good (maybe will need some adjustments to be faster- sort and delete all 0 itemes in the same time etc):
