Setting up a SHT-10 temp & humidity sensor with ThingSpeak

Troubleshooting

Hello,

I am trying to set up the SHT10 sensor with ThingSpeak and having some issues. I ran the tutorials and all worked ok but I cannot seem to log any data from the sensor to ThingSpeak. I have placed my code below for reference. Please help and yes I am new to coding so my apologies in advance.
