You are using string array. However, I think you only need to show one of the element at a time. You can try to use [code] if (step<(n2-1) ) { scaffoldtxt="Largest number that can multiply "+ i1 +" that is =< "+tv[2*step+1]+" ? "; scaffoldtxt1="Largest number that can multiply "+ i1 +"*"+(int)(Math.pow(10,(int)(Math.log(i2/100) } [/code]
