The Slider block lets a visitor pick a number by dragging a handle along a range, with a matching number box for precise entry. This article covers the range, step, default value, display format, and how percentage sliders scale.
What it does
A Slider shows a track with min and max labels plus a number box. The visitor drags the handle (or types in the box) to set a value within your range, and that value is substituted into the block's assigned cell when the calculator runs. Dragging and typing stay in sync.

Settings
Formula

General
The General group has the shared title, description, and hover hint controls. See Common block settings.
Value
- Display as — Number, Currency, or %; picking Currency reveals a currency picker. See Number formats.
- Range — the minimum and maximum of the slider, entered as Value to Value. The minimum must be less than or equal to the maximum.
- Default value — where the handle starts. If left empty, the slider starts at its minimum.
- Step — the step size between stops. A step of
1snaps to whole numbers;0.5allows half-steps; and so on.
Percentage sliders
When Display as is set to %, the slider displays values as percents (0–100) but substitutes the decimal equivalent (0–1) into the spreadsheet. Enter the range and default as whole percents — Numio handles the conversion, so a slider sitting at 25% feeds 0.25 to your formulas. Write your formulas against the decimal value.
