 * Hi All,
 * I have an ordering form on my [infographic designer](https://www.infographicsdesigner.nl/bestel-een-infographic/)
   website.
 * It used to work, but now the calculation has stopped working. Click a tickbox
   and nothing happens. It should add the price and the tax rate (BTW in Dutch) 
   to the total but it doesn’t.
 * Can someone help me with this and point me in the right direction?
