Yes, looks like your sorting method works. It seems to me that it is only sorting 5 of the numbers from 1 to 6 (ie. 1, 2, 3, 5, & 6 -or- 1,3,4,5,&6) and 49.
So, we need to fix your random number generation, not your sorting.
First, change your array from 1 .. 49 to 1 .. 6. Then, we want to create 6 random numbers (from 1 to 49) and assign them to our intnumbers array. But, each time we create a random number, we must check to see that that number is not = to any of the previous random numbers that we've made. Use a loop and an exit command to do that.
Essentially, you'll have your loop, then your random number generation line, then a little more complex code to check if the current element of the array is equal to any of the previous elements of the array. I suggest making a function to do this, but it's not necessary.
I hope you can understand that. Post any further questions if you have them
