Going nuts trying to find the syntax error! Help!!

I've been looking for the syntax error in this snippet for hours. Can you spot it?

Here's the page (last section only; "Fiberglass Boattails"). Select an item to show inputs.

Please help. Thanks.

                               //find FNC Slotting in array
            for (var i = 0; i < productArray.length; i++) {
                if ((productArray[i][0]==SLOTTINGFNC)) { 

                    document.getElementById("FBTLslotting_price").value = productArray[i][2] //price per slot
                    break //this exits the loop since we found what we're looking for
                }
            }
            
       // Putting together total slotting prices for display
       
   FBTLslotting_price = FBTLslotting_price.substr(1); //remove $ sign
   var TotalSlottingPrice = Number(FBTLslotting_price) * document.getElementById("Fslots").value ; //multiply price x qty
         
                //The prices below added together for display
           document.getElementById("FSLOTpriceDisplay").innerHTML = "$" + TotalSlottingPrice.toFixed(2); //put $ sign back, display total price
