Thanks for the quick response.
I cannot use a hyperlink as the form is emailed to different users for approval and final processing and these users do not have access to common share drives.
What I am trying to do is under certain conditions, a .csv file is created on the users local drive and then attached to the form in a file attachment control (there is a reason that this data needs to be captured in a seperate .csv file and not on the form). The user is then able to open this .csv file, input some required data and then send the form to a mail recipient.
Using infopath 2003 and vbscript, I am able to programmatically create the file on the users local drive but I am not sure of the code required to attach it to the form. Any help would be appreciated.
