I gave that a try, nothing appears in the "solution" field. ? Probably something I did, dunno.

thanks for your help

Post your sketch, you must have missed something....

paste it between the code markers ( <> on the menu above the message compose box)

thanks for your help

enjoy !!

EDIT : I did it as multiply, not divide, modify to suit

Sorry I have no knowledge about this stuff, just trying to learn.

So, I cant display the result or i can? you have me confused.
I was going to pay someone to write the code, but if it cant be done it would be good to know before i get scammed by someone who said they can do it.

thanks again

Sorry to confuse you....

Let me put it simple....

An "Edit field" allows you to send data into the controller - you will not see any changes that the controller may make to that data until you restart the app, so you cannot use en "Edit field" to display data coming from the controller.

There isn't a display field that can display numbers, there is only a "Text String" display, so the result of your multiplication would have to be converted (in your Arduino, or whatever, code) into a String (of characters) data-type, and displayed on your app as a "Text String".

What you want is perfectly possible, but it highlights a limitation iimposed by the controls available, and their capabilities.

..... It was just to make clear that i was using 3 input fields. My interface is 3 floats at the moment.

That's the problem, they are input fields only, data direction is one-way, so the input field never shows any values that are in the controller, except at "Registration" when the app reads the data from the controller.  After that you can change any input field's data in the controller, and it won't show on the app.

thanks

ps; that is not the interface i'm using. It was just to make clear that i was using 3 input fields. My interface is 3 floats at the moment.

The values you put in the top two boxes will go into floating point data in your sketch.

Divide them as you want, and then convert the result to a string to display in the bottom box.

Note : You cannot use an "Edit" box to display anything coming FROM your controller, the interface is not bidirectional. Edit fields are mobile device data TO your controller data.

IMHO this is a poor interface, you have no clue that what you have entered into an Edit field has actually arrived at the controller

i want to divide the top 2 fields and display the result in the bottom field.

Can this be done in remoteXY?

thanks everyone
