I'm using APEX 5.1.1. I need to access a page item while preparing a page process success/fail message. I tried to add the item with "&p10_name" or ":p10_name", but that does not display the actual item value.
That is a use case for static text substitution string references. These must be in uppercase and terminated with a ".":
Bind variable references in SQL and PL/SQL (
:p10_name) are not case-sensitive.
Here's additionnal information to what fac586 said.
