Thank you - that worked. However I now have another problem. I was able to save the Insert Plug-in. You can see it in my server behaviours list as 'Static Plug-in (appliancetypeUpdate). I am now trying to add the Ajax Functionality - I have selected the select field in the main page and gone to WebAssist >Framework Builder but I don't have the option: Framework Builder > Load Plugin to Div. See attachment. I have saved the the file and closed it and opened it again but I just don't have that option.
