Inventory Program Part 6

8
I'm having some trouble with my inventory program. Its due tom and my teacher is not wanting to help. He keeps giving me a soluction that is not related to my code. I have everything working except the Delete and Modify Button. The Search button works but it only searchs the new .dat file or what is set in the array. Not sure what is going on there. But if I can get my delete and modify button to work that will be good.

Code....
