From what I get:
He'd like the program to do what I did in my capx, but in a way he can understand the events..
The value is changed, not in the string, but in the variable.
The string is only used to display the value of the variable.
Changing the value of the variable, will automatically change the display of the value within the string.
So when the x2 is clicked, the value of the variable is changed to 2x the original value of the variable.
when x2 is clicked a second time, the value of the variable should be changed back to the original value.
The string displays the value of the variable and because the value changes, the string displays the changed value.
