For everyone that has this error in the future just going to pure html button and typing in the code you want still change the -> to html thats whu it didn't work
so you have to press the small button under the tinymce editor where it says Turn WYSIWYG on/off

thanks again
and one more question if it does not fit here please move it where it belongs:
in 1.2.4b multi language support I have added formbuilder.
the question:
do you maybe know which files the code has to be changed to be able to support fileds descriptions in the appropriate language? is there a quick hack except creating the same form for every language?
or can I put additional fields in db like formFieldNameHolder_langID?
thanks again
