VBA Push Buttons and Tick Boxes in MS Excel 2007

Hello all I'm uber new to VBA and I'm looking for some help with the programming!

Firstly I'm looking for the code that I can apply to a button so that when pressed it will add 1 on to a number in a specific cell with the reference AK7.

And secondly I don't know if this can even be done however here goes......
I would like to set up 7 "tick boxes" and a button that are linked such that when the button is pressed it carries out a macro attached to each tick box that is selected!



hope this makes sense and someone can help me!
