Accuracy Graph not working

I’m trying to Run my DL model on my dataset following the instructions from the video but for some reason My Accuracy Graph does not load. I’m sure i got some setting wrong.

I have attached pictures of my network architecture and also a screenshot of training page.

Any suggestions what I can do to get it right ?

Also find my nework architecture attached:

Hi can you share the configuration of the model and the hyperparameters used.
It might be because of the loss function used for the above regression problem.
