If/else sorting problem

subconix (3)
I posted in this forum a few days ago about a program I was having trouble with.
"A user enters 3 numbers, the program will sort the 3 numbers in ascending order and descending order, displaying both orders to the user. Only use if and else statements, no arrays,or anything else.

So i figured out how to code this, but it only works in certain instances.
if i enter single digit numbers in the order of 1,3,2 the program sorts it in the correct order with no problems. However if I start entering larger numbers in the order of 1000,700,950 for example. My program completely skips the second number. Why is this?

check out lines 44--45.

Also, you ignore some cases when calculating the second number.
For example, c < a < b
