It wasn't clear from the initial post that this was a javascript error. but now i see it.
the error is caused by these two lines:
var Member Inquiry__1_Spry = new Spry.Widget.ValidationCheckbox("Member Inquiry__1_Spry", { isRequired:false , validateOn:["blur"]});
var Questions or Comments_Spry = new Spry.Widget.ValidationTextarea("Questions or Comments_Spry", { minChars:1, maxChars:300, isRequired:false , validateOn:["blur"]});
the reason it is happening is that you are using spaces in the form element names. Spaces are not permitted in form element names.
when naming the form elements either conform to the camelCase naming convention or use the underscore (_) in place of spaces.
