i have 2 variables

var num1 = 1;

var num2 = 1;

no i also need to increment the numbers in a for loop.

but i also need to use these variables as a string for this code

num1 = num1 + num2;

which i should get "11" instead i am getting "2"

it is just adding them together.

on the other hand if i define the variables as num = "1";then i cant seem to increment the numbers.

how do i go about this
