Hi good day to all of you, I'm currently working on an app to plot a graph based on certain value inserted. For value fo, the user have choice to use the slider to select the values they want or input their own values within the limit of 4 to 36. When it comes to the coding part, how can I take either both values and yet assign to the same variable which is fo, so far I've assigned fo to both of them but one of it doesn't work, is there a better way to do this ?

When the Slider is moved, its callback will be invoked. You should set the EditField value in the callback to keep them consistent. Similarly, when then EditField callback is invoked, you should adjust the Slider values.

I suggest using one callback function for both objects. You can use the event input to determine which object was changed and the function will merely update the other object.
