There is such a type of 'number' for input tag. Not sure where you got the idea from??? Anyway, a suggesting revised code is below. The function takes the form ID and obtain input values from the form's input elements. The 'correction' is 'readonly' so user wouldn't accidentally change it. This form use 'button' to call the function. You could use onchange() event, but that may be confusing for you right now. Hope this help.
