## Objective
Verify invalid target values are rejected when target is enabled.

## Preconditions
- See [[PRE-DF-cp-editing-form]]
- And target is enabled

## Steps
1. Enter zero, a negative number, or a non-numeric value, then attempt to save

## Expected Result
- Then the system rejects the input and blocks save (a target value is required when enabled)

## Source Traceability
- TSD: PK141
- Section: C6 - Target Modification
- Scenario: C6.4 - Target validation
- Acceptance Criteria: PRD C.24 Scenario 1-4

## Evidence Required
- Screenshot of rejection for each invalid value.

## Notes / Gaps
- No gap.
