Validation Issue: Rank Field Accepting Negative Values

[sandeshlavshetty]

Description:
The rank field in the form currently accepts negative values, whereas it should only allow natural numbers (positive integers). This is causing unexpected behavior in the application. The expected behavior is to validate the input so that only natural numbers (1, 2, 3, ...) are accepted.

Steps to Reproduce:

1. Go to the form where the rank field is present.
2. Enter a negative number (e.g., -1) in the rank field.
3. Submit the form.

Expected Behavior:
The rank field should validate the input and restrict it to natural numbers only. Negative values should not be accepted.

Actual Behavior:
The form accepts negative values for the rank field without any validation errors.

Suggested Solution:
Add input validation for the rank field to ensure only positive integers are allowed.
