setting s.evar in custom code does not work

Question

I am trying to set an eVar using custom code in Launch through the Analytics Extension. So far, nothing is working, no matter how I try to set it. I see the data that I want in the console, so I know I am receiving it correctly. Is there something I need to do differently or include? I see the test string for the link track as well... console.log("%c ******", "color: red; font-size: 20px");
_satellite.logger.log(event.element.getAttribute('data-acid'));
let evarValue = event.element.getAttribute('data-acid') || "No Data Written";
_satellite.logger.log(evarValue);
// s.linkTrackVars = "eVar87";
s.eVar87=evarValue;
s.tl(this,'o','Link Track in JS v2 Test')

Hi @justcallmepcra12,

I set eVars in Custom Code all the time, so I know it works.

However, I can see that you are sending a custom link, so you will need the s.linkTrackVar to be set (it's currently commented out), but if there are other dimensions / metrics also being set by the Adobe Extension, all of them will have to be set in the declaration as well.

For instance, if you are using the Set Variables to set eVar1 and prop1, instead of just:

s.linkTrackVars = "eVar87";

You will need to have:

s.linkTrackVars = "prop1,eVar1,eVar87";

(order doesn't matter)

To ensure that the Custom Link sends all the dimensions on the tracking call.

Where is this code being added in Launch? It is inside action of a Rule right? I am checking in case this isn't somewhere (like a Data Element) being executed before the s object is ready on the page, which could be causing the last two lines to fail.
