Hi Author,

The only way to do this is using the OnChange() client script, Could you try the below approach?

1.) First set some default value for your number variable

2.) Write onChange() client script on another variable

function onChange(oldValue, newValue, isLoading, isTemplate) {

if(newValue) { //If another variable is not empty
var number = g_form.getValue('number_variable'); //First fetch the default value from the variable
var incrementNumber = Number(number) + 1; //Number() function is used to convert into number
g_form.setValue('number_variable', incrementNumber) //Set the incremented number

}
