July 13, 200421 yr Hello, Hope someone can help me: I have a backoffice system for travel agents. When itinerary is made I put reservation number for identification. When the invoice is arrived I search for the reservation number and then I run an automatic script with Replace function. But, here could it be a problem. If something happen all posts could be replaced which would damage a lot. So I would write a calculation so I can see how many find posts have the reservation number. If the find post and calculated value is same the script will follow with the replacement. If not the script will end. Please, do anyone of you know how I should write the calculation? Thanks in advance. -Per
