Every pack must pass these checks: it needs a name and a number of meals (Every pack needs a name and a number of meals); its price must be above zero ("<name>" needs a price above zero) – the builder exists to stop $0 packs going live; if you set a category split, the counts must add up to the pack size (the category split adds up to N meal(s) but the pack holds M); and if you enter a regular (compare-at) price, the selling price must be below it (the price must be below the regular price). Fix the highlighted row and press Create these packs again. Repricing an existing pack changes only its two prices and leaves its other options untouched.
