Hi Mildred,
User Input Contols (radio buttons, checkboxes, combo boxes) were added in version 6.1 of XPression. You would need to upgrade to this version to use this new feature.
You can contact
techsupport@rossvideo.com to upgrade your XPression. Tell them your current version, what XPression software you are using, and if you have the serial number of one of your XPression units that will help them find what software packages to send you for the upgrade.
You add User Input Controls to your graphics while you are designing them. Once you've added them to your graphics the users in Inews will be able to use them. The users can then use the different input controls to change the content of graphics or how the graphics look or behave.
