Value specified is below 0%

Error message

Value specified is below 0%

What it means

Companion to [97]. In set.barWidth() (progress.js:405-407), if value < 0 the module logs error.tooLow and skips setting the width. Percentages below zero are invalid for the bar-width setter.

Solutions

1. Pass a non-negative percent to 'set bar width'.
2. Clamp with Math.max(0, value) before the call.
3. Use 'decrement'/'set progress' which normalize internally instead of feeding raw negatives.

Example fix

// before
$('.ui.progress').progress('set bar width', delta); // delta = -10 -> [98]

// after
$('.ui.progress').progress('set bar width', Math.max(0, delta));

var pct = Math.max(0, Math.min(100, Number(value)));
if (Number(value) < 0) console.warn('barWidth clamped from', value);
$('.ui.progress').progress('set bar width', pct);

When it happens

Trigger: Calling $('.progress').progress('set bar width', -10) or passing a negative number (e.g. from an overshooting decrement or a signed computation) to the barWidth setter.

Common situations: Decrement logic producing negatives; signed deltas; subtracting a larger from a smaller value without clamping; feeding raw sensor/counter differences that can be negative.
