I am using two "indexOf" functions to find the row and then the column of the data I want to replace. Code is as follows:

var timeIndex = lookupTime.indexOf(apptTime)+4;
var terrIndex = lookupTerr.indexOf(apptTerr)+1;

var overrideStart = masterAvail.getRange(terrIndex,timeIndex).getValue;

However, the "var OverrideStart" gives me the result of: function () { [native code] }

Please help!
