Activate the workflow.\n2. Open the **On form submission** node.\n3. Copy its **Production URL**.\n4. Paste the URL into the **Set URL** node, replacing `REPLACE_WITH_PRODUCTION_FORM_URL`, so the **Calculate Again** button redirects back to the input form.\n\n---\n\n### Calculation Methods\n\n**Profit Margin**\n\nCalculates the selling price required to achieve a desired profit margin after taxes and fees.\n\nValidation:\n- Tax + Fee + Profit Margin must be less than 100%.\n\n**Markup**\n\nCalculates the selling price using the desired markup percentage over the product cost.\n\nValidation:\n- Markup must be greater than or equal to 0%.\n\n---\n\n### Customization\n\nYou can customize:\n\n- Currency formatting\n- Pricing formulas\n- Form labels\n- Validation rules\n- Styling (CSS)\n\nThe calculation logic is located in the \"**Calculate - Profit Margin**\" and \"**Calculate - Markup**\" Code nodes."
