# Fishbowl: Cost cannot be negative

> A cost value in a manufacture order is negative when it should be positive.

## What it means
Fishbowl prevents saving a Manufacture Order when any cost value (material, labor, overhead, or similar) is negative. This validation catches data entry errors or sync mistakes from suppliers or other systems.

## What to check
- Look at the cost fields for the part listed in the error message
- Verify any costs you entered manually are positive numbers
- If costs were synced or imported, check that source for negative or unexpected values
- Clear the negative value and re-enter the correct positive cost
