Vba tip:

Good coding practice

It is important that you always comment the VBA code that you write. By doing this it will make the code much easier to read, as both yourself and other people will be able to see what the code is doing or meant to be doing. This is very important if there is more than one person who writes code in the company as you may have different styles of coding and may not really understand what the other person is trying to do. Also if you write some code and then do not touch it for a year or so you may actually forget what it is meant to be doing. so it is very important to include comments throughout your code and try and make sure that they are as useful as possible
