how to display button values

[merituulimelkko]

Hi! Not sure if this is what you were asking, but text that is displayed on a button is determined by the label property, which you can set in the right side bar when the button is selected. If this didn't answer your question, please explain in a little more detail what you are trying to do and what you have already done.

Hi! In the build apps that iam design the calculator app, i have taken o to 9 number buttons and operation buttons. one input box is taken and bound with buttons, when the button is clicked, the number is displayed only once in the inputbox.

[merituulimelkko]

So if I understand correctly, you are only getting the first number into the input? Or just one number at a time? Not sure about what you have set up, but you should have a page variable bound to the input's value and then a set page variable with some formula to do a calculation operation on top of the page variable's value. What sort of formula are you using for the number buttons for example?

[jyothigogada]

Yes, for example when i click two times on 7 button, only display in input box one time. I given the button formula "NUMBER(pageVars.num7)".

[merituulimelkko]

Alright, so that formula would only set the most recent number into the page variable. You would want to append it to the existing content, so the formula should be something like `pageVars.theVariableYouUseToDisplayWhatYouWantDisplayed + "7"`.

Hi merituulimelkko thank you.

but this formula show the value only like "77", but i want all the times as many times as clicked. Please solve this problem. thank you so much.

Hi, I will need more information to be able to help you further, because the formula I provided you works when I tested it. Here's a working example, e.g. first button sets page variable `result` with formula `pageVars.result + "1"` and the input field displays `pageVars.result`.
