Showing part of a variable(numbers)

So i have a name stored into a variable. Lets say "Tomato" in variable 1.

I am able to store part of it in variable 2 with $gameVariables.value(1)[0] and another in var 3 with $gameVariables.value(1)[3].
when i call var 2 and 3 in text it says ta.

However when i put a number in variable 1 it doesnt work. Why is that and how can i change it?

Edit: How do i turn the number set in variable 1 to a String? Its the thing i was trying to do beforehand be cant remember

I imagine it would work like that if you changed the number into a string?

You can enclose the number in "" so that it saves as a string instead

$gameVariables.set(index,"number")

so for example

$gameVariables.set(1,"500")

Well ive got as far now as:

var i = $gameVariables.value(1) + "";
$gameVariables.setValue(1, i);
------------------------------------------
By doing(var1 is 12345):

$gameVariables.value(1)[0]
$gameVariables.value(1)[1]

Allows me to do what i set out to do.
By storing:
($gameVariables.value(1)[0] + $gameVariables.value(1)[1])
inside variable 4 says thats 12 is inside it.

So my next question: How do i turn the now text: 12 into a actual number again?

Number(stufftochangetonumber) does that :) e.g. Number($gameVariables.value(1)). So you can use it as a Script>Control Variable or simply within your scripting block. Whatever is easiest.

and String(stufftochangetostring) works the same, for reference.

Solved it. Thx both of you.
