The replacement value is user dependent, i.e. when an input field is used on a server, different users will see different sets of input field values
That means that if the document is deployed on the server there's no way to store the changed values to a qvd.
If the document is opened locally with Qlikview Desktop then your script should store the changed values according to this post.
Thank you, Gysbert. I have deployed my document on the server to test and you confirmed my suspicions that I am unable to store input fields by trying to store them in a QVD.
So now that that option is thrown out, what other options are available to store input fields? Any suggestions are welcome because now I'm stuck!
