Farmers Market Program Part 4 frustrated and confused about SKU numbers

[blondielox]

I have pretty much gotten my program to run with one little exception. It is asking for the SKU number which has been set but when I run the program it assigns a number to item and does not give me the sku number I had entered in the program.

I have tried various things and nothing seems to work or I wind up with many errors. Can someone please look at my code and tell how to fix it!!!! I am at my whits end....

There are 4 files in the project

From what I can figure it has something to do with the for loop in the last file that starts on line 142. I don't know what to do to change it to not assign a number to each item and to give me just the sku number that is set in the array.

You need to try debugging your code by adding some printlns to it to show how the values of variables are changed and how the execution flow goes.
