Anthony, that error is produced when I change the field line like i show
above. I basically need to know how to change this list:
['Line: 324 ~ tom', 'Line: 246 ~ dick', 'Line: 112 ~ harry']
into this html:
Line: 324 - tom
Line: 246 - dick
Line: 112 - harry
The problem seems to arise when I try to use XML() with a json object.
I'm trying to add a <br> in between each item in the list, but XML()
doesn't seem to play well with JSON. How could I accomplish this?
