I am afraid it does not go in that order:
"webassist -> Forms -> Validation -> Validation Show If. for the Validations Fail condition, select All."
My options are:
webassist > Forms > Validation > Server Validation >
Then I suppose
Validation trigger: "Any form post"
Validation Type: "Required / Not Blank / Selection Made"
Server variable: ?
I tried but it did not work "WA Validated Entries"
(BTW I do put forth effort trying to figure this out before I post here)
