I did this EXACT tutorial or whatever a while back, but i made mine so i can change team names and put homeruns and keeps track of homeruns/runs. was pretty funny.
a tip when adding numbers (E.G. 2+5) Use the Cint() function
so code would look like
Cint(text1) + Cint (text2) = Label1
or something like that.
otherwise if you do text1 + text2 = Label1 where text1 is 2 and text2 is 5 then the answer would be 25, you need to use Cint() even if you dim text1 and text2 as integer.
