# How to validate a range in my Flow form?
## This article guides you through validating a number range in your flow form.
In this example, the field is valid between 5 and 15.
#### **Step 1 — Build the valid range condition**
Drag in the field from the form layout, drag in the `≥` operator, and enter the minimum value, 5. Drag in the `AND` operator, drag the field in again, drag in the `≤` operator, and enter the maximum value, 15:
```
(data["Number"]>=5)&&(data["Number"]<=15)
```
- Dragging in the field from the form layout
- Drag in the 'greater than ≥' symbol
- Enter the minimum value 5
- Drag in the 'AND' operator
- Drag in the number field from the form layout
- Drag in the 'less than ≤' symbol
- Enter the minimum value 15
#### **Step 2 — Set the rule to Valid**
Click on the "Valid" word to configure the outcome.
#### **Step 3 — Set the status, colour, and message**
Set the Form Status, colour, and a message if needed.
**Note:** The Error status will not allow the user to submit the form until the field is valid.
****
#### **Step 4 — Add the catch-all invalid rule**
Invalidate everything outside the valid range:
```
1==1
