How do you do level nine on roller coaster creator

1: Use the 'climb up' to go up to the highest diamond
2: use the 'corkscrew right' to the line with the dynamite on
3: Where the two diamonds are at the bottom, before you get the the end, just on them 2, put a line (a long one)
4: Use the 'Steep climb up' to get the the flag.

If you understand ANY of this and you no how to do it, you will get the end of level nine. Thank you
