How can two if statements that work perfectly standalone as single statments.
Make outcome that differs when you put in, an else if statement to only execute one of them. The below statements have the statement with heavier conditioning first so not the second statement gets executed. Because both satisfy the noneboolean condition.

I probably done some very no no thingy.

 	

if (EDITEND<SELEND && document.getElementById("lockedit").checked){
  SELLENGTH=SELEND-SELSTART;
  document.getElementById("SB").value=EDITSTART+SELLENGTH;
  document.getElementById("EB").value=SELEND;
} else if (EDITEND<SELEND){ document.getElementById("EB").value=SELEND;}
