So i did some testing and I can upload to the board but once i plug the shield into the arduino, i get errors, not allowing me to upload. I want to point out the the shield covers all the pins on the arduino but nothing is currently plugged into the shield. What are the possible solutions to have the shield and arduino together to interact with the usb connection. Yes drivers are updated, Port is correct, and board selected is correct. Do i need to cut the pins from the shield that go into pin 0 and 1 of the arduino uno (since they are the digital pin). Below is the error message i receive and have looked up solution, but none are helpful due to the problem not involving a shield:

Problem uploading to board.  See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

So an update, it will upload when i switch to softserial, but when i go to UART i wont upload. I need UART because that is the only way my sensor will relate to the shield. Also was given weird character readings.

So incase anyone has this problem, all you have to do is upload the code with the switch on softserial. Once the code is uploaded, switch to UART and the program will function correctly on the board.
