Hi Jakub. I'm glad it worked out for you. Everything that I know about VBA, I learned on-line. Forums are a great source of help and information. I have found that by doing searches, I can find pretty much what I need and by putting it into practice and doing some tweaking, I can get it to work. Just to give you an example to go along with your case, if you searched for "hide rows excel vba", I'm pretty sure that you would have found a solution. There are also many on-line tutorials that are of great help. Good luck with it!
