RE: Witango-Talk: Deleting empty Rows in Array
Okay, the problem is I need blanks in the middle.

Probably the best way to do that is in a while loop - check to see if @RIGHT numchars=2 = ; and cut them off if it does - and loop until it doesn't Robert _ From: WebDude [mailto:webd...@cipromo.com] Sent: Monday, January 04, 2010 3:16 PM To: witango-talk@witango.com Subject: RE: Witango-Talk: Deleting empty Rows in Array Okay, the problem is I need blanks in the middle.

Witango-Talk: Deleting empty Rows in Array
Hi Folks, I have another one I have been working on and I am having a devil of a time trying to get either @filter or any type of filtering on text strings to work correctly.
