Hi there,
That error is because the goals and current fields can’t be left blank, so you’ll need to put a number in the “Your Goal” and the “Current” field (can’t enter 0 must be at least a 1 in the “Current” field.

Once you enter your goal and at least a number 1 in the “Current” field that error message will go away.
I’m going to address that error on the next version of the plugin so either you can’t leave it blank or at least it generates an error message that explains that clearly.
Hope this helps! Let me know if you have any more problems or questions with it. Thanks. Alan
Right! Thank you so much!
