zaicatku VBA code Option Explicit

zaicatku ? I do not know what it means.

Option Explicit

If you put this at the top of your code, you need to declare all variables you are using within a code. If you do not , you get an error saying there is undeclared variable.
You can make it as default in all your macros by going to Tools-Options-Editor.
