Hi guys, I have a form ("InfoEntry") that gathers data (a "weight" and "quantity" field) via user input and plugs these values into an equation that figures out a total charge. The result is stored in another field ("charge") within the same record. Each time the user creates a new record and enters in the data, the charge is calculated for that record. I'm going to shift the user entry process to a PDA/mobile device that will allow users to input the "weight" and "quantity" information when away from the PC - with the expectation that at the end of the day the information will be imported into Access. I have the data importing into a separate table ("daily import"), however I now need to run my equation on each these new records (I can't run the "charge" equation on the PDA).... So, I'll need to run the equation which takes values from "weight" & "quantity" and store the result ("charge") in another field for *all* the existing records imported (on a record-by-record basis). This will happen before I finally append these new daily records to the "main" table. I was hoping someone might be able to give me some pointers on how to actually construct the mechanism that I need to be able to do this? I'm thinking that I'll need to use the MODULES section, but I don't know where to begin. I have used the VB code editor to run the equation in my InfoEntry form (as each new record is created), but I'm not sure how much of this knowledge can be applied to the MODULES section?? Any help would be greatly appreciated Thanks in advance!
