Use this option, which is only visible for projects and not for standards, to toggle the display of variable expression errors, such as those shown below.
Variable expression errors
These could be displayed when opening a project or when starting the Parametrics Editor. This can happen when a project, containing variables, has been exported from one Impact system and then imported to another Impact system. This is particularly an issue when the receiving system has a different standards set installed compared to the sending system.
The toggle acts on a per project basis, so if you switch off the visibility of errors for one project, they would still be displayed for another.
Don't display these messages again
You can also switch off the display of these messages from the form.
