Hello friends, I'm new to appinventor and programming, I'm trying to put a query that contains parameters but I'm not getting it, could you help me please?
follow the blocks
php
APP FIELD
the response content is not what you are expecting...
therefore the for each in list loop will run into that runtime error
before using the for each in list loop, check if global_json_listar is a list...
you can find that block in the List drawer...

if is a list global_json_listar

else display a nice error message
