What does line.... "PK" mean?

Thanks for all the helpful responses. I had a feeling it was something like zero, but I wanted to be sure. Of course, I was lazy, and could have just looked at the line in a sportsbook.

What happened is that the "PK" broke my database insert when my machine was scraping the line.

I know, I'm not as cool as most of you all software engineers scrapping data from all over the internet. But like you most said, we all must start somewhere.

But thanks again to those kind fellows that helped me out.

The only dumb question is the one not asked, many of these haters need a handbook in regards to going south on a woman. Best of Luck to you tonite brother. 

Y'all are getting trolled

It means you should not be sports betting! But who do you like? 

What does ML mean?  

Many of you are not friendly, he does not know that's why he's asking .

GL to you too brother!
