Hi.
Iām trying to attach statistics to an external object, but the doc example is not very clear and javascript shows errors 
Without alert(ffr); I get error in filter file, line 45, t is undefined
this.attachEvent("onEditCell",function(stage,id,ind){if (stage==2 && ( ind==i || ( i && i[ind])) ) f.call(this);return true;})]);t.innerHTML="";}; And in custom function, without c = āā; I get c is undefined error.
Any insight or advice on this?
Greetings and thanks.
