I have been looking through the forum still cant work out how to create a Yes / No question. I can get the question to pop up when the user clicks button but regardless if i click yes or no it does what the yes button is meant to do. I have created an eftpos button to ask the user if the payment was approved or not. if its approved (Yes) then finish the sale, if no is clicked it goes back to the payment screen. from what I have found it looks like its meant to be simpleto make. but has got me stumped. is there a full tutorial on how to make a yes no question with input?
