Problem loading multiple xml files from one javascript.

Hello krpano specialists,

Based on the “cmp-pillars-of-creation.xml” example, I need to load different scenes from a javascript.
Depending on the user's actions, I need to load different scenes on the left and right. The scenes are grouped in xml files.

Unfortunately, in addition to my basic xml file, I can't load my 2 xml files with the scenes:
krpano.actions.loadpano(“2019/panos/sec_1/comparepanos.xml”, null, “KEEPALL”);
krpano.actions.loadpano(“2014/panos/sec_1/comparepanos.xml”, null, “KEEPALL”);
Keeps only 2nd...ans one error to load the seconde scene (normal).
I also tested with “MERGE” or “ONLYSCENE” ... nothing works... I have this message in console : ERROR: 'layer[krpano1]' is not an Object!

Can you help me?

Thanks Tuur
This is not the problem krpano1 and krpano 2
I solved the problem by concatenating the xml in a variable and I use loadxml and it works fine.

Bonne suite à tous
