thanks for the reply. i was doing it wrong. this syntax worked for me
in the end:
var imgDesc = Form.getInputs(theform, 'text','imgDesc');
var imgTitle = Form.getInputs(theform, 'text','imgTitle');
but i actually realised i could do the processing i needed in php so
am not using prototype to do this.
