Editting Macro To Select Last Empty Column To Paste Data

I have a macro that automatically takes data from one sheet, copies it and pastes it on another sheet, but I want it to select the empty column that is to the right of the last column to contain data (so basically the next empty column). What code would I enter into editting my macro to be able to do this please?

Also, one thing I've tried to do with my macro is that when I select the data, it's suppose to select from the first name to the last. When doing the actions for the macro, I use "Ctrl + Shift + Down Arrow Key" to make the selection select the bottom of the list. However, when running the macro, if the list is longer (or shorter), the macro selects that number of cells instead of the action of just going to the bottom of the list. For example, if during the actions of the macro, I recorded using the Ctrl + Shift + Down Arrow Key that 50 cells were selected...next time if I have 60 cells, only 50 are selected, even though I used an action command which should select all the cells in that group (in this case being 60). Is there some code I can add to that so this would work correctly?

In case its required, here is the code from the macro:
