custom event trigger in google tag manager -

every time create custom trigger event doesn't fire. can please may reason. have created 'gacustomevent'custom triggerand have name 'gaevent' event not getting fired. iwant use event in datalayer capture value. advice on how issue resolve

it's bit unclear question how set up. should this:

datalayer.push({    'event':'myevent' }) 

(this assumes datalayer initialized).

in gtm go "variables" section. in boxes predefined variables hit checkbox in front of "event". you're ready use custom event in trigger.

go "trigger", select new -> custom event. in event name box enter "myevent" (as per example, substitute own value).

the custom event works when there key/value pair in datalayer key "event" (that's kind of 'reserved word' in gtm). event name value key.
