real quick i hope

Could I get some help?

Variables:

tierletter> is a variable the user inputs

numbertochange> is a number that the user inputs

orgtier> is the original value

I got all the information I need I am having trouble with one step(see below), I need to add the numbers together that are held by numbertochang and orgtier

so if tierletter = q

numbertochange =20

orgtier=4

the result should be q24

(strcat tierletter (+ (itoa  numbertochange orgtier)))

I just cant get the 2 numbers to come up
