jquery.js:3869 Uncaught ReferenceError: small is not defined

[coderius]

My code in html: <input type="checkbox" name="my-checkbox" checked>

And jquery script: $("input[name='my-checkbox']").bootstrapSwitch({onColor: 'primary',size: small});

Bun it is not working. In console : jquery.js:3869 Uncaught ReferenceError: small is not defined If I delete params in bootstrapSwitch like: $("input[name='my-checkbox']").bootstrapSwitch(); It works fine and no errors in console.
