Image Maps

I’ve been trying to get the “comic has map” function to work.

I check the “*Comic has Map?” box. Comic-has-map comes up in the list of custom fields. The value is set to 1.

I replace the 1 with my html. I hit “update” in the custom fields section, then update the post.

My html is gone. The 1 has returned.

I tried keeping the 1 and putting my html after it. The html disappears.

I tried adding an additional comic-has-map custom field and put my html in there. After updating, my html is still in the additional box, but the map doesn’t function in the comic.

Is there a step I’m skipping? I changed the map name from “map” to “comicmap,” as seems to be suggested, but that didn’t change anything.

The map should turn the gray area above this comic into a link:

Thanks,
Chris
