Can anyone help me please?

You need the computer to read the blank sheet... and if you go back to the book shelf, it will have a couple of important things on it... Like at the right shelf tap the boxes to find the old guest registers... check the red book in the middle of the shelf... It's called "Life Trivia"... It has some random folk-wisdom, including some instructions on how to sharpen cutlery...

Examine the blue book above "Life Trivia" to trigger a cut-scene... Your now trapped in the room... Quickly examine that blue book again to find that it's titled "Osterzone the Phantom Painter"... Surprisingly this is written by Robert Evans... You will keep this book into your inventory... While doing so, you will also find something in between the pages...

It's a photo of Dunning and Jenny... Double tap to add the photo to your inventory... There's a date written on the back of this photo... It's may 18 1967... Now... Head to the computer machine... Keep pressing the power button to try to turn it on... Unfortunately it isnt working... Turn your camera to the right to find the power cord
Connecting the machine to it's socket...

Double tap on the cord to find that it's indeed connected... However the connection is loose, which is why the machine isnt working... Check the red toolbox underneath the table to find a hammer... Take it... Quickly check the top drawer to the left of the machine... theres a box inside... But it's locked... Youve got the code though... It's
518... You got it from the back of the photo... You will find an old envelope in the box... Pick it up to find that it's a letter from Robert Evans to Dunning... At the end of the letter you will find some codes... Now... Check the bottom drawer... You will find a file, and a pair of scissors...

Choose the pencil from your inventory and use it on the file... Simply move the pencil up and down until you gather enough graphite powder... Use the graphite powder on the power cord... When the screen zooms in tap the connector on the ground
To sprinkle the powder over it... This should improve the contacts
On the loose plug... The machine now will work... Check the
Paper to find that words are written with invisible ink on it... Now get out of the puzzle... You can't solve it while the screen is zoomed in...

Instead use the black light on the Paper (close the DS kinda...) and you will see a number on it... The number is randomly generated... You will now need to punch in the code you found on Evans' letter earlier into the machine... To make things easier use Evans' letter on the machine this will make the letter appear on the other screen... once that is done touch the power button to turn the machine on... Now turn the number dial to the number that you saw on the paper... You should now type in the code using the keypads on the machine... After you finish one line tap ENTER to move to the next line... When done you will decipher the hidden message on the machine: "Osterzone is... Dunning Smith..." Louie will then come to your rescue... Just head to the door and touch the door icon to get Out of here.... The whole thing has a time limit though... So be careful...

Please help I've done everything in the basement I'm stuck on the computer the number on the paper is 72 and is the same every time I've died, I enter the code on the letter and then I've tried the numbers but as it's 2 numbers I tried 7 and then 2 and enter and nothing happens! I've tried it the other way round it just repeats the code then goes back to a blank screen and then I die it is really annoying me coz I've tried every number combination possible please help!

It,s not 72 it,s 12
