invalid input
Unacceptable entry received
Invalid input is data or a response that doesn't meet expected requirements—wrong format, out of range, or otherwise unacceptable to a system or process.
Computers reject invalid input with error messages; forms flag it for correction.
The system displayed "invalid input" when she entered letters in the phone number field.
The phrase appears in technical contexts but has spread to casual use for any response that doesn't compute: I asked what he wanted for dinner and got invalid input—just a shrug.
