      use a variable to hold the value

      var x = 0

      WoonplaatsCell.innerHTML = MWB.x.plaats;
      or use a literal

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

        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)
