OK - that's no problem. Is there a button - to the left of the screen - which says 'Free'? Just touch that, and then you'll be asked if you want to install it - hit 'Install' and the iPlayer app will automatically download and install itself on your iPad. That takes about a minute or so. You'll be asked for your iTunes password - I'm assuming you're doing this from your iPad - and then the download will start. The screen will change to your iPad Home screen and a dim icon of the iPlayer app will appear on the screen and initially it will say 'Waiting' then it will say 'Downloading', then it will say 'Installing' and, when that's finished, you're good to go. Touch the iPlayer app and it should open up and you'll see all the TV programs that you want to watch.
Again, get back to us if there's a problem - we love hearing from you...
