Fishbowl: Cost value must be positive
Error✕
The cost cannot be negative.
OK
What it means
You’re trying to enter a negative value in a cost field. Fishbowl doesn’t allow negative costs—any cost amount must be zero or positive. This usually happens when entering a unit cost, average cost, or similar costing value.
What to check
- Verify the value you entered: check whether a negative sign got included unintentionally
- If you meant to enter that value, confirm whether you actually need a positive number
- If you’re trying to reverse or adjust a cost, look for an adjustment or reversal transaction type instead of entering a negative value
