Restricting save filenames to stop changing the original file.

So I am fairly new to VB and up to this point I have been able to Google what I needed and modify it to my needs but this time I wasn't able to get it to work right.

So I am in need of some code that will block a user from saving the file with a certain name. Basically I have created a master work book and when someone uses it they need to save it under a different name and leave the master template blank and intact.

I am thinking when they try to save with the original file name you get a message box and then it cancels the save. but I want it to do this on save and and save saveas
can any one help me out with this or point me in the right direction with some sample code?

Welcome to the forum!

If it is a template, why not save it as an xlt or xltm file?

To be honest I had never thought of using that as a solution and wasn't completely sure how to implement it. So I googled a little last night and the problem im facing is that even though I save it as a template. when you open and forget to save as a different file name.(just click save) you still change the original file which is what im trying to avoid in the first place. The whole reason behind this is that I work in a office of people who are not very computer savy and formulas links to cells and information gets changed a over written fairly often. So I have created a Master Packet with all the formulas, forms and such in it to work from. but sometimes they forget to save the changes as a different file. it is my understanding that this is what a template is suppose to do but I must have been doing something wrong because after I saved my file as a template I was still able to edit and save it just as I had done before.

So after playing around some more with the template idea you suggested yesterday I figured out what I was doing wrong.
I much appreciate the reply/suggestion as this will do exactly what I was looking for. Thank you and I apologize for my ignorance.
