      No luck…
      I’ve tried both of the options:

      	var MWB = this.MWB;
      	var n = 0;
      
      	// creating the tablerows
      	var WoonplaatsRow = document.createElement("tr");
      	WoonplaatsRow.className = "woonplaats-row";
      	
      	var WoonplaatsCell = document.createElement("td");
      	WoonplaatsCell.className = "small";
      	WoonplaatsCell.innerHTML = MWB.n.plaats;
      	WoonplaatsRow.appendChild(WoonplaatsCell);
      	table.appendChild(WoonplaatsRow);
      

      Error: Uncaught (in promise) TypeError: Cannot read property ‘plaats’ of undefined

      	var MWB = this.MWB;
      
      	// creating the tablerows
      	var WoonplaatsRow = document.createElement("tr");
      	WoonplaatsRow.className = "woonplaats-row";
      	
      	var WoonplaatsCell = document.createElement("td");
      	WoonplaatsCell.className = "small";
      	WoonplaatsCell.innerHTML = MWB.['0'].plaats;
      	WoonplaatsRow.appendChild(WoonplaatsCell);
      	table.appendChild(WoonplaatsRow);
      

      Error: Uncaught SyntaxError: Unexpected token [

      So both of the options give an error.

        @htilburgs said in Uncaught SyntaxError: Unexpected token return:

        WoonplaatsCell.innerHTML = MWB.[‘0’].plaats;

        sorry, my bad, try these

        WoonplaatsCell.innerHTML = MWB[n].plaats;
        WoonplaatsCell.innerHTML = MWB['0'].plaats;

          @sdetweil YES, that did the trick! Learning a lot these few days.
          Thanks again.

          Is this notation always like this if you’re working with numbers?

            @htilburgs not so much numbers, but variable data… the notation

            MWB.n.plaats
            

            means the plaats element of the n element of MWB
            so the dot notation treats the between dot things as literals…

            a number can’t be a variable name literal in this sense…
            so, you need the bracket notation [] (and remove the left side dot when u use it this way)
