Brilliant thanks meratigoerr. I've amended it slightly as the images will always be held in the same location so now have
Code:
Me.txtImageName = "\\servername\share\pictures\" & Me.Username & ".jpg"
as an After Update event on the "Username" field which is now appending the value entered here to the end of the defined network path into the txtImageName field as I wanted. Thanks again....How can I thank you on the post as there doesn't appear to be a star at the bottom of the post frame!?
I didn't mean hide the txtImageName field, I meant hide the network path shown in this field so that only the filename that's getting appended appears!
@June7: I already have an Image Frame with a control source reading from the txtImageName so wanted to auto-populate the field based on the username which is also the same name as the image that will be stored on the network drive.
