How to add up selected choices

[the_scott_mans]

I was wondering on how to add up selected stuff.

Ex.
A list of items

1. Xbox
2.Gamecube
3.PS2
4.PC

say the user selects 1, 3 & 4 well i want it to add up just those. By adding i mean PRICES

If I make any grammar errors, please correct it. (it's been a year and half since I've done Turing)

code:

// variable declarations omitted XBoxprice := 299 GameCubeprice := 199 PS2price := 259 PCprice := 799 loop     put "Please input selection: "     get selectitem     if selectitem = 1 then price += XBoxprice     elsif selectitem = 2 then price += GameCubeprice     elsif selectitem = 3 then price += PS2price     elsif selectitem = 4 then price += PCprice     else break // nor this end loop put "Total price: ", price
