I have a 3x3 array of text fields whose values get transferred to an int array. I need to make sure that integers 1-9 each occur once within the int array. Any ideas on how to go about that? I could do it by verifying that every int is between 1 and 9 and then adding them up to see if the total is 45. There are two problems with that: First, eventually I'm going to add code to highlight the first invalid number found (whether it be a duplicate or an int other than 1-9) so I'll need to know which number is invalid. Second, I know there's got to be a much easier way than that. Any ideas? Thanks in advance!
