which is used when the user clicks a checkbox that I have made. I would like the text to be appended to the reply form at the end of their message, depending on whether or not they have clicked the checkbox. Currently, the .innerHTML is not working when there is text already in the reply form but it works when the reply form is empty.
Has anyone got any ideas on how to do this? Maybe there is a text variable that stores the user’s message that I can append to – if so what is the name?
