I'm designing an app in which you select some input variables and its values, and after clicking the button calculate, the apps calculates and shows to the some physical values that has calcuates. (e.g: ypu enter as inputs m,g,h,a (and its values) and after clicking "calculate" it shows you F (force) and ME(mechanical energy) and their values.
So, here is are the dropemenus where the user can select the inputs he wants to enter and at the right, their values.
The issue here is that, by default, those white EditField(Numeric) windows (on the right), has the 0 value on it, as you can see above. The issue is that I would like those windows to be empty until the user enters one value. Is this possible? I have tried clicking on each windows's Inspector panel as you can see below and changing its value 0 by just deleting it
But appears me this error.
So. It's possible to have those windows empty until the user enters a value? Or is any alternative way of achieving that?
Thank you very much
