Suppose the name of your string is s. Then you can do this: s.charAt (0)+":"+s.slice (1) P.s if the first number is less than 10 you need to add a zero before it . like for input 456 it will be 04:56

does this work for input integers or only strings? I get the error message "d.charAt is not a function"
