Arduino connected to an HD44780 compatible LCD display, error code prob

I have tried two different wiring arrangements(one from the playground), & # different sketches.I’ve gotten the same error code all 3 times; Avrdude: stk500_getsync(): not in sync: resp=0x00 I have tried to look this up to no avail. Paul S from this forum taught me a lot about programming, but i’m still a newbie - any help would be greatly appreciated! I will include the sketch attachment from the playground, as that’s how I have it configured at present. the display is a standard 16 pin, 2 line, 16 character HD44780 compatible as required for this sketch. I believe i’ve covered most everything, but if you need more info, I respond quikly!
Thanks in advance,

This is a problem uploading to the arduino, not necessarily with the LCD.

Can you upload without the LCD connected?
Can you post a schematic of how you have the LCD connected?

Your computer and your Arduino are not communicating. Have you selected the correct com port? Is the Arduino connected? Can you upload if the LCD is disconnected?

ok, thanks guys - I’m busy for a few hours, but will disconnect it & make sure i’m on the right com port. I have another arduino also I could try. will post results & wiring diagram tonight.
thanks,
Daniel
