Using functions not working

I think I may know the problem, you are using script blocks within your function, eg mixing ASP and HTML within the function.

Try changing the entire function to ASP using response.write to output the HTML, if that fails, try placing the code from the RTE_editor_inc.asp include file directly into your function.

I have never tried calling an include file containing a function from within a function as I have always believed it to be bad programming practice, and so it maybe this reason why you are getting the error.
