I have Nintex form with a Choice column that has multiple checkbox enabled where the user can make multiple selections:
] Repetitive ] Non-Repetitive
I want to have another field "WireType" require a value if 2 checkboxes above is selected values. I created a validation rule below but it doesn't work. What's the correct rule to apply? I'm appreciated for your help.
WireType == "Repetitive" && WireType == "Non-Repetitive" &&
isNullOrEmpty(Amount)
I also tried this rule and it doesn’t work:
contains (WireType, "Repetitive") && contains(WireType, "Non-Repetitive") && isNullOrEmpty({Self})
