Show Field Over an Amount
How It Works
- What it does: Shows or hides the field depending on the Amount.
- When it shows: The field appears when Amount is over 1,000 – handy for an approval field on large spends.
- When it’s hidden: Amounts of 1,000 or less keep it off the form. Form-only – it doesn’t block saving.
Common Use Cases
- Revealing approval fields on large amounts
- Threshold-based capture
- Spend-based form logic
- Risk-driven fields

What does this formula do?
Show over an amount. It runs on the form, showing or hiding the field based on the trigger value.
Which columns do I need to set this up?
You need: Amount (Number). The formula reads these to produce its result.
Why is this formula syntax different from the others?
Show/hide formulas use SharePoint’s JavaScript-style syntax – [$InternalName], == for equals, && for and – rather than the Excel-style syntax used by calculated columns and validation.
If LookBook 365 is code-free and out-of-the-box, why does this example use a formula?
A SharePoint formula is native, declarative configuration, not custom development. It only works with the item’s own fields and simple logic – it cannot run scripts, reach external services, or change other data, and nothing is deployed to your tenant. It keeps working through Microsoft updates. If you would rather not set this up yourself, this is exactly the kind of thing I configure for clients.
