I need more time, it's possible?
Another question: when I try to print, while I'm submitting the form I can't see my answers in the multiline field. My you help me?
More time than the 28 days? No, 28 days is the maximum setting for the Save Web Form but a user can Save and the retrieve the saved form within the 28 days and then save again giving them another 28 days.
Printing the form from the web browser isn't something we support and it does not work well. To print a form the best method is to have a paid level subscription and use the "Download Response as PDF Form" feature on the View Responses tab to download a PDF of the response where the multi-line text fields have all been expanded to fit the text.
