Error from LCD serial

Hellow guys , i am following http://www.instructables.com/id/Arduino-Shooting-Target-Game/ , and i managed to assemble all things, the console in ARDUINO IDE gives me all ok, it all works.

BUT I GOT 1 PROBLEM the SERIAL LCD i got is different from builders LCD , and i canno't get to a conclusion on how i got to change code.ERROR HERE ( - YouTube) after seaching the old interweb i managed to find my ADDR is 0x3F , i loaded up a example code, the lcd works, then i loaded up the code from programmer with minor adjustments and the LCD gave me the message i wrote up.

I WILL ADD THE ORIGINAL CODE

I WILL ADD MY MODIFIED CODE THAT GIVES ME SOMETHING ON SCREEN

My problem is .. how do i edit the menu and things to use my LCD... i'm....busted... i'm a low level user, trying to find my ways, but if someone can help me with the code... mby we can get to an agreement.

I modified code and it gives me TRYING OUT ..and clears.

Can i leave the code? my LCD is serial as well, but it's like i can't get to it

Thank you very much guys, and hope you have a great day.

I'll move this to Gigs & Collaborations. I expect you will need to find a library for the LCD you are using.

Hellow , yes sir, if you take a look at the photo i uploaded, i already found and put in library.

The LCD is working ( showing something) ... but i do not have the knoledge to change the whole code, that is why i was asking for advice...mby a short lesson, i can't understand, how do i change the original stuff ( like number of target hits , the timer , etc ) from serial.write to lcd showing ..

As i said i am very new to this, i wanted to learn but after some major health problems , i had to ditch the arduino studies ... more time in hospitals than learning..so as i said before..is someone can point out... mby help me .. i could pay something for the time... Thank you all

NO ONE ? A FULL FORUM OF USERS... and just NO ONE to help me. :(((( ... if i can't find help here...i'm giving up . As i said i don't have alot of money , but i can pay something for mby 1 hour of help ? ..

i only need to change the lcd from the owner's one to my lcd code
