No problem with your code.Its running fine.
But you are not sure what you want
1)The inventory.ini file is opens only for record count purpose.you are not reading any data from the file.
2)The code is not fully complete.
As of now its fine.Clarify you requirement and finish the code 1st.
Thanks,
DP
