I have a canvas that shows a university campus which has a ball on each building, i would like to create a code where i can click on the ball and at the top of the screen it shows the amount of computers available in each building, and then i need to create a cancel button that adds 1 to the computers available but can only be clicked if you click reserve first, and also a reserve button which takes away 1 from the computers available. I am having great difficulty doing this and would really appreciate any help. I find the blocks way too hard to do because i have not used or been taught about this software at all. :(

A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook http://www.appinventor.org/book2 ... the links are at the bottom of the Web page. The book 'teaches' users how to program with AI2 blocks.
You will not find a tutorial, which does exactly what you are looking for. But doing the tutorials (not only reading a little bit) help you to understand, how things are working. This is important and this is the first step to do.
