there are multiple text input boxes and multiple buttons on a screen for a Calculator app.  
Using the “Any Component” block how can I check that whenever a button is clicked all the text\_input boxes are non-empty and numbers(not text)

Welcome to Thunkable.

If you add **0** to the content of the `Input Text` you will get a **NaN** error if the text content is not a number. You could make use of this condition to validate the content as numbers.

Is there a reason you’re using text input instead of static button text (0-9, +, -, etc.) for your calculator entry?
