Data to display in one cell when specific data from another cell is selected.

Hi Guys

I have a rather specific problem here, I apologize If I have posted this in the wrong part of the forum.

I am making a table / calculator to calculate total costs over a 24 month period for a paid service (mobile phone service), now there are different levels of service which get different amounts of calls, texts and data.
Now I have it already set up so you can select the different tariff prices to calculate how much you will pay / tariff price and phone costs combined ect ect, basically all simple addition and multiplication formulas.

What I want to know is, is there a way that when I select the tariff price the worksheet will then display what tariff I have selected? (how many calls texts and data)
I have feeling that its possible, I'm just not sure how to go about implementing it.

It would help if you could post a small sample file showing expected results and explanation the logic behind any calculations.

Click "Go advanced" the Paper Clip Icon. Then "Add Files" ==> "Browse" (select file) ==> "Upload" then "Done"

Thanks for the reply, I have a screen shot of the worksheet for you.

Where the top arrow is is where you select the tariff, there are 8 tariff options (9 including 0)

Basically when I select a tariff from the drop down list, is there a way for the small table by the bottom arrow to then automatically display the amount of calls, texts and data you get for that tariff?
for example, the tariff selected would get you 300 Mins of calls, Unlimited texts and 300Mb of data.
