Hi Arthur,

What event is this script running in, the calculate event?  It looks ok to me syntactical , but haven't you the condition

if (attachments !== null) {

around the wrong way, look like it should be

if (attachments === null) {

You should get a line number in the error message, have you dropped that off when pasting into the forum?

yes i run it in the calculate event on the server side.

there is thre error message ->  Error: Invalid property get operation; field doesn't have property 'dataObjects'.

when i initialize a variable like var doc =; i dont receive any error , but when i add dataObjects i receive an error like  Error: Invalid property get operation; field doesn't have property 'dataObjects'

i changed the if statement but i receive the same error.

Probably can't help with any server side questions, I haven't done much and haven't an environment to test with.

But, your error does seem strange, like you have a field object called myDoc which is confusing the JavaScript engine. Is that possible?

Also there should be a line or two before that message which gives the context of the error, something like;


Maybe a screen shot will help.
