You're incrementing noOSCUnits then attempting to use that as an array index, when that array element doesn't exist. The third  line above is trying to use OSCUnit[1] when there is only 1 item in the array, OSCUnit[0].

But you should also be testing that you're actually getting an OSCUnit object created, and that manually-incremented noOSCUnits counter seems a little prone to trouble too, when OSCUnit.length or OSCUnit.push (to add an item) gives you the array size directly. So, assuming you want OSCUnit[0] to be named "OSC1":

if(obj = patcher.newobject("bpatcher", 300, 100, 300, 100, -220, -30, "OSC Unit.pat", 0)) {
noOSCUnits = OSCUnit.push(obj); // 1
obj.varname = "OSC" + noOSCUnits; // "OSC1"
// note obj and OSCUnit[0] still refer to the same object
}
else {
post("error: no OSCUnit returned");
}
