TypeError: Assignment to lists with more than one item is not supported

Trying to replace a blank with a default code:



var mvx = tmp=msg['RXA']['RXA.17']['RXA.17.1'].toString()



if(mvx=='') {

// Enter blank MVX

tmp=msg['RXA']['RXA.17']='UNK^Unknown manufacturer^MVX';

}

tmp=msg['RXA']['RXA.17']['RXA.17.1'].toString();

tmp=msg['RXA']['RXA.17']['RXA.17.2'].toString();

tmp=msg['RXA']['RXA.17']['RXA.17.2'].toString();
