Ok, a few things I noticed....
1. You are using a very old version of Odin. I recommend only using 3.07 or 3.09.
2. The COM port box is yellow, which probably was trying to caution you about something.
3. You have a Sprint model S3. This is the T-Mobile S3 forum.
4. You have a Sprint S3, but were trying to flash old T999 firmware! This simply will not work, and if it were to flash, insta-brick!
What you need to do is start using the Sprint forums. Only flash items you find in those forums, and nothing else. While some of our roms might flash and boot on yours, they will never function very well. This is one of the things the asserts in an updater script are intended to protect against.
Finally, just a bit of posting advice. Please use proper punctuation. Small mistakes are ok, but posting with no punctuation at all just makes it difficult for people to read, and many will just close the thread and move to the next without bothering to help.

Oops! Just realized the pic in the op wasn't yours! But still, theyre all good points you should check before flashing. Also make sure kies is uninstalled or disabled on your computer.
But most importantly, you need to be in the Sprint forums. We can help a bit here, but you need to ONLY use stuff from your devices forum. And a lot of it we simply may not be familiar with.
Good luck!
