I've deleted the other two threads as there's no need to ask the same question in three different places.
You need to overwrite the existing hex value with a new one. A few basic ones for larger amounts (like $80 mil, for example) are included in the tutorial for easy reference. So basically, you're finding the existing salary cap value and changing it, but both figures need to be converted to hex first. If you've found the existing salary cap value, you're halfway there.
