Error Message when trying to build a custom form

Hello,
The CE is working on a custom form for my client Gordon Flesch and after she drag and drop the drop down box over and she typed in the question and hit save I get these error messages.
I'm working on their site for OE.

The name of the form should be: 2018 HRA
the field name should be : Did employee complete HRA for current year?

and the drop down list should consist of: Please make a selection, Yes, No
