JavaScript: what is the function of "length" in this case?
Because the error says "null or not an object".

Re: JavaScript: what is the function of "length" in this case?
Is that the correct way to declare an array?
try
conv_tbl = new Array(63,63,63...);

This was the original coding:

But I had to change it to somehow make it fit for my database recordset. (I use ASP)
Here is the altered version of the javascript. I took out the 3rd textarea, which is html_area, and all the red sections. But it then gave the error:

Re: JavaScript: what is the function of "length" in this case?
after this line of code
mc = document.conv_form.mc_code.value;
try alert(mc); just to see if it contains anything.
