Hi, hope someone can help me!
i've downloaded some code for a wysiwyg editor it's called HTML areas, unfortunately there is no longer any support.
i have several textareas (that are wysiwyg editor) on a asp page. (see below)
what i'm tring to do is submit the form. to a page and then update the record in the db.
like this:
(i've only given one example of the insert query, i didn't want to hold the record for the logest thread!)
my problem is that if the user dosn't physically click in to the three <textareas> then it dosn't work.
is there any way to get around this? please help!!!!
the textareas look like this (3 of them):
and...
with the following script at the top of the page:
and this Javascript file....
