I am really new to programming in C# and my knowledge at the moment is pretty limited. I have been doing a project for college regarding a flight booking system in which I had to make two planes that can take bookings and give costs for this.
The only problem is I finished it all but foolishly forgot that I needed two flights, but instead I have just made one. I thought it would be easy enough to sort by just making a button that could switch between the two forms and then just copy the form exactly for the second flight. Sadly this was not the case and I keep getting this error message
Error 1 The item "obj\Debug\Scotia.Form1.resources" was specified more than once in the "Resources" parameter. Duplicate items are not supported by the "Resources" parameter. Scotia
As I said my knowledge is limited and I have no idea what this error is. Any help on how to duplicate the form succesfully would be much appreciated as everything else i have got running fine as well the code for the button I will be placing on the forms. Thanks In advance
