Cell value change to zero when reading them

[stemanticsllc]

When I click on the button "Plot me Scotty", the numbers in the cells become zeros If I print the values of x & y I get 2 lists with zeros. Any insight into why this is happening? I would like to populate a sheet then plot columns against each other by clicking a button.

Thanks
