MCP_Lib Arduino Uno r3 w/ CAN-BUS shield DEV-13262 from SparkFun sendStat =-7

I have checked to make sure the circuit, baud rate, mghz, pin usage, and connections should be correct. I am using an Arduino Uno R3, a Globe Motors EPS system, and the CAN-BUS Shield DEV-13262 from Sparkfun to try and send a message. I keep getting exit flag=7 for the first 3 attempts, and then it switches to exit flag=6 for the rest. Is there some error in how I am trying to send the message? Any help or suggestions are appreciated.

Your code was small enough to post inline.
