Simple question:
Is there any way to convert a string to a variable? |

Umm, not sure that's a simple question. You have a variable that say contains the string Mystring and you want to create a new dynamic variable called Mystring? If that's the case I would guess the answer is no. |

What i'm trying to do is to open a file, say My file.txt that could look like this:
13
23
4
15
and so on...
Then pick a number at a time using Loop, Read, adding that number to a variable (Sum) and finaly showing the sum of all those numbers! |

Ok, based on your question you already know how to read the file, in your loop just add the strings
Myvar += %A_LoopField%
Not sure if the var is right but you should already know that part. |

| Code: | loop,read,numbers.txt
{
if a_loopreadline is not number
continue
sum += %a_loopreadline%
}
msgbox,%sum%
return |

Although it's not related to the question at hand, you can create a variable dynamically. The method is the same as that for creating arrays. The simplest example is probably:
Dynamic = MyNewVar
%Dynamic% = Value |

Cool! Didn't know you could do that! |

Jonny got it right
but the test is not necessay. Ahk automatically assignes the var as a number. if its not numeric it simple returns a zero
ie.
12
3
23
some text
3
4
; a blank
3
returns answer 47 Et voila!
| Code: |
loop,read,numbers.txt
{
sum += %a_loopreadline%
}
msgbox,%sum%
return

Eh, show me up, will you? Well then, take this!
| Code: | loop,read,numbers.txt
sum += %a_loopreadline%
msgbox,%sum%
return |
Re-optimization! The brackets aren't necessary for one line! 
That return isn't entirely necessary either, since AHK has "fall-off" support, so this is a three-liner. |

I can't believe I didn't see that return. Well spotted sir. Mind U I didn't write the script did I, only corrected it.

I actually meant the return at the end. This is a valid AHK script:
| Code: | loop,read,numbers.txt
sum += %a_loopreadline%
msgbox,%sum% |
