Okay and what are the results YOU are getting, I can easily find what I get but it's your results that count [or not] (pun intended)

Click to expand...

Yeah many times, it is only a simple fixed or variable width text field [CHAR(255) or VARCHAR(255) [ Preferred ] needed and an UPDATE or INSERT query.

However, it can't be done with javascript, (this being the js forum)
