sum values and forward to the text

I'm trying to add the values that are inside the [valuetext] with the next one of its element, but it returns the value inserted there and not the sum.


what do I do ps. [valuetext] is float

Code (CSharp):

1.         switch (Index)
2.         {
3.             case 0:
4.             {
5.                 __text.text = valuetext[0].ToString();
6.             }
7.  
8.             break;
9.  
10.             case 1:
11.             {
12.                 text.text += valuetext[1].ToString();
13.             }
14.  
15.             break;
16.             case 2:
17.             {
18.                 _text.text += valuetext[2].ToString();
19.             }
20.  
21.             break;
22.             case 3:
23.             {
24.                 {
25.                     _text.text += valuetext[3].ToString();
26.              
27.                 }
28.             }
29.  
30.             break;
31.         }
32.     }

 

Just to get an idea here, are you trying to concatenate strings, or add floats (numbers) together?

 

in the post above it does just that about passing float (numbers), the problem is to sum each value to the next in the list and pass it to the text
