Yes, i clicked the last reply, and was just making a general responce. Sorry.
Second, order doesnt matter... If the second isnt preset, or the first--still gett he same message. My pattern of thinking is go check from the last paremeter to the first. If your missing the last one, then alreayd right there you can halt processing. If you have the first, but then dont have the second, it took that much more power in parsing to check the first, then the second--rather than halting after one condition. I know, I know, one if statement--how much memory could that use. but hey, when you have seveal of em, it kinda make a difference. >:D
