i can't understand it. how to solve it.

[Shafique]

i have to save the weight a stack of sheets. So i want to do it in MS Access that's why i create a database with only one table named "tblweight"
i set three fields in my table
1..........ID.........Autonumber
2..........QTY.....number
3.........weight...number

In QTY textbox i put the number of sheets of every stack
here i want a after update event on [QTY] that get that weight scale data into [WEIGHT] textbox that connected with my PC via a COM Port
i search the solution on internet and get this code but it is not compiling. how its works

any solution or suggestion

Well I would expect you would need to open the port, before you can read from it?
You would most likely need to write first for whatever is on the other end to tell it to send the data?, so you need to read up on the device instructions?
