Hi there,
I have a strange situation. I have a direct call rule that fires after a data element change rule. In this direct call rule I set a bunch of eVars.
I was setting them in the eVars section of the rule builder. When testing I could see the eVars populating in both the network requests and Omnibug. However I wanted to change it to minimise the risk of sending in unspecified values.
So I added to my custom code the following type of rule for each eVar I wanted to set:
var dataElementName = _satellite.getVar("dataElementName");
if(dataElementName) {
s.linkTrackVars = "eVar1";
s.eVar1 = dataElementName;
}
However, this only works if I add one rule of this type to the custom code. As soon as I add another rule with the same syntax it doesn't set either eVar. It's almost like it can't see them at all.
We use this kind of thing a lot in our custom code and it works reliably. I can't understand why in this situation it's not setting the eVars.
Any help would be greatly appreciated

Hey Philip,
The s.linkTrackVars variable is a string containing a comma-delimited list of variables that you want to include in link tracking image requests ( tl() method). I believe the reason eVar is not set when same piece of code is written again is because it resets value of linkTrackVars.
For instance:
s.linkTrackVars = "eVar1";
s.eVar1 = dataElementName;
will set eVar1
s.linkTrackVars = "eVar2";
s.eVar2 = dataElementName;
this will only set eVar2
To fire both the variables on the same server call, the syntax should be:
s.linkTrackVars = "eVar1,eVar2";
So, in gist you would need to append the values in linkTrackVars than resetting it to new one.
Hope this helps!
