Hello, I have a select_one variable on my ODK form. 1.I want to count the number of all options any ideas

Counting choices in a static select doesn't make much sense, does it? If the choices are static, then the person designing the form knows exactly how many there are (as you pointed out previously, @Xiphware ) . The counting is only useful if that count can actually change.
