Infinity08 your comments are really helping me understand this better. Could you please let me know if what I wrote is going on here is correct. I can't seem to figure out exactly what this wants, except know it wants a string that is length 6. Thanks again

I'm not sure if it is taking each character in the string and adding them up and the sum should be 58, don't know so because when I type ASDFGH the ending value is 43 in ecx. Thanks again
