You can, but it only seems to work in a web browser.I did the following test case:Created variable called Str1.Created variable called Str2.Created a text box.On Show, set NewStr equal to Str1. (No delay)On Show, Add to NewStr the value "\r". (Delay 0.5 seconds)On Show, Add to NewStr the value of Str2. (Delay of 1.0 seconds)On Show, Change Contents of text field. (Delay of 1.5 seconds)The end result works fine in the web browser, but not so with the preview.Kevin
