Thank you alot for helping. But I still have the problem where I need the increment as you've provided, and as well as with the error message for the starting number being less than the ending integer. I do not understand at-a-boys or girls. But this is how I see what is needed. If Start < End (something about a negative increment?) Start =End =Increment = -1 < how do I get the error apge to show the -1 on increments... due to the start being smaller then the end.Error Message Else If Start > End (something about postive increment)Start =End =Increment = -5 2015105 Do exactly what you provided me, but in increments of 5. which I know is just changing 1 to 5 i think. Others have said something about the algebra changing the increments because of the negatives. Again I am a newb. I'm taking this course to learn, but out of 5 assignments this is the first to stump me. I also appreciate you stopped to take time to help me on a Sunday night. It's not due until Tuesday but I do have a array program to learn and write by thursday if anyone would be open to it when I get this one sorted out. I honestly need a friend to one on one with so I have a spotter to smack my hand with a ruler when I do something wrong then explain to me why. I added what I changed to the file for what I've progressed from your help. The If statement is needed from what I'm aware of, as well as, an Else and another If. Sorry for drama. I just didn't expect a response so fast. If I had known you were on I'd loved to pick your brain to ehance my own. Also apologies for not be very specific. <!DOCTYPE HTML> <?php /********************************************** Author: Dylan T.
