Need Macro to calculate cost when user select an option

[HarryC]

Hello
I want to build a template where i have various options in tiles that a user can pick and then chose categories underneath the particular option which will have a cost set and then picking various categories will calculate cost.
In a perfect example just how we chose our tv packages.

So, for example -
I have a one of the master category called "Resilience" . there will be various other master categories.
if user clicks on "resilience", underneath it, it gives various options to chose. Example SPOF, 2 DC Manual, 2 DC Auto. I want user to see the definiton of each
And then allow user to pick any of the above. (behind these there are cost for example SPOF - $100, 2 DC Manual - $200, 2 DC Auto - $300)
and if the user select any of the option, there is a sum total at the bottom which is calculating the cost.

Hope i have managed to explain what i would like excel to do and hope it is simple

Thanks again
Harry
