I am attempting to scrape data from multiple website pages into a list, then add that list to a table. The problem I am having is that some items are missing from some pages, the bot then goes to the next page and continues scraping. Then when the list is posted to the table those missing values causes the data not to line up in the correct row as the missing values are not skipped in the table. So the question is, how do I put in a placeholder for the spots when I scrape something that is not actually there. If you can't tell, this is completely new to me. Thanks for your help. define

There are form by default has a value. http://img689.imageshack.us/img689/1835/valuec.png If i put the new value there, not replace/delete default value, but only add the new one in front/end of default value. I tried use $replace $nothing to delete but unlucky. How can i remove OR replace 'em?
