ListView subitems problem... finds column but throws error.. DRIVING ME NUTS!

[C# Programming]

I cannot figure this out! It is driving me nuts!

Ok so I can do a IndexOfKey and get the index (which in my case is 24), but when I try to get the text it gives an error:


int index = 0;
index = lstImport.Columns.IndexOfKey("Category");

MessageBox.Show(index.ToString()); // THIS SHOWS 24

if (index == -1) cmd.Parameters.AddWithValue("@Category", "");
else cmd.Parameters.AddWithValue("@Category", lstImport.Items[i].SubItems[index].Text); // THIS ERRORS


ERROR:

System.ArgumentOutOfRangeException was unhandled
Message="InvalidArgument=Value of '24' is not valid for 'index'.\r\nParameter name: index"
Source="System.Windows.Forms"
ParamName="index"
