Re-enable Right Click Options, Disable Cut Functions

I need a macro to disable all cut options (ctrl^x, right click cut, cut button in ribbon above), disable drag and drop, but still allow copying and pasting (the cutting affects cell references). I've already locked the spreadsheet, but users need to be able to input information and paste information in from other workbooks. This code must also only apply to THIS WORKBOOK and not affect others. Please help with a macro for this, as well as where to paste and how to properly configure macro security settings. I'm a big excel user, but this is my first time ever with VB and macros so talk to me like I'm dumb! I've pasted links to the two codes I tried, and I think one of them enabled a macro that affected all workbooks and now whatever code I put in won't save upon re-opening. It's there when I navigate to it, but it is ineffective like it's not even there. In macro security, I've enabled all macros and have the "trust VB programming" box checked. So maybe do some damage control before re-programming. I am getting a new computer in less than a month, but I want to be able to try out the code and have it work first, and I don't want to transfer the harmful code to the new computer.

P.S. This first code allows copying and cutting, but then just disables pasting, which is not what I want. The second one works great, but disables the right click menu altogether, which is no good either. And neither allow for pasting from the outside. And this is for moderate excel users, they won't try to erase the macro. I just need to keep them from making mistakes with cutting.
