Merge two column with text separating two value

I got macro (thanks to this forum) to join two selected column and I need to put x to separate both values. How to do it?

Thank you for that, but above macro is only part of actual code I need to accomplish to generate my spreadsheet as I need it. Is there way to incorporate function into macro?
Sorry but I am mostly Auto CAD user and still thinking CAD way when creating any programing.

Just bumping - I really need it, please.
