Lenny Conundrum 182

Starting in the upper left corner and ending in the lower right corner, solve this maze. If a number is divisible by 2, you may move up. If a number is divisible by 3, you may move down. If the number is divisible by 5, you may move left, and if the number is divisible by 7, you may move right. You may not traverse a number more than once.
What is the sum of all of the numbers you cross on the way to the finish?
Answer-check: Sum of digits of answer = 11.
Hint: Excel + IF(boolean, string, string) + (MOD(integer, integer) = 0) + the little corner draggy trick = love.

okay, is it saying:
a) if you are currently on a number, and the number to the right is divisible by 7, you may move there. If the number downward is divisible by 3, you may move there.
OR
b) If the number you are CURRENTLY ON is divisible by 7, you may move to the right, or if the number you are CURRENTLY ON is divisible by 3, you may move downward.

wow. thats crazy.... i tried a technique of working backwards, but im finding dead ends
And yes, when going backward, i take a number, divide it by 3, and THEN see if i can use it to continue my path working backwards.... i divide the next number on my backward path, not the one im currently on like i would be doing when working foward..... and yet, ive run into dead ends. i cant figure it out.... and i thought i had a nice strategy going there.

I'm pretty sure it's option B, which is what I used for my answer, and it seems what you're doing should be option B too. If you're finding all dead ends, you messed up somewhere....
Manually calculating is horrendously tedious and I really don't recommend it....

Phew. Thanks for the answer check, I needed that 
And at 3am I need to sleep!
Edit:
Okay, I did it by making a map, and I have no printer so I had to draw it out by hand :K And then putting arrows going to each of the squares I could travel too.
I hope that makes some kind of sense. Like I said, 3am!

ugh, i'm getting more than one way to solve this. anyone else having the same problem, or are there multiple routes that just add up to the same number anyway?
EDIT: got it. i had messed up one number and it threw off my whole path.

My path is not k yet 
Getting crazy here!

I thought that I had done this correctly. I checked my path multiple times, yet the sum of the digits of my answer is 17 and not 11, as in the first post of this topic. I'm going to cry if I got it wrong

This took me awhile, I just drew it out, numbers in pencil then penned the avaliable directions ... i'm just worried ebcause it was alot of adding at the end to get the total number, I might have made a mistake like that!

This is easily solvable with patience, but here's the fast way to produce a maze. Using Excel, create one 9x9 box using the formulas shown in the highlighted area. The formulas produce the " | " and " -- " cells by seeing whether the mod of the center number equals zero - if it's zero, it shows the symbol, else it shows nothing. Then highlight the 9-square of tiles and click and drag the little black box in the lower-right corner of the selection, which copies this box over and over (so first make a column, then across for the whole maze, or vice versa). Type in the numbers into the cells.
Then I printed the maze and solved it by hand. The orange formatting was added manually to highlight the maze solution. The numbers below the maze helped me add up all the numbers (In each column, I typed the numbers which were highlighted, then summed each column up, then summed the row of subtotals).
This may be easier to see the maze with (options -> gridlines):
Major edit: 9:09 PM EDT, much better explanation of how to do it.
