How about putting some console.log in it to see what's happening:

      for (var c in p2inp) {
        console.log("Input type: "+p2inp[c].type);
        if (p2inp[c].type == "text") {
          temp = counter + count + 2;
          console.log("Temp: "+temp);
          tempor = p2inp[temp];
          console.log("Tempor: "+tempor);
          temporary = values[counter];
          console.log("Temporary: "+temporary);
          tempor.value = temporary;
          //inp[temp].setAttribute("readonly", "readonly");
          //inp[temp].setAttribute("disabled", "disabled");
          counter++;
        }
      }
    alert("The code HERE gets executed");
    console.log("removeButtons should now execute");
    removeButtons();

if it still doesn't execute but the last alert and console.log gets run then check the removeButtons() function for errors.
