Can someone explain... ? (conditional branches)

Hello!

In my application, I have 2 branches with the following logic:

1. If the message ERROR IS null - branch to Page 5
2. else - stay in Page 7

If I use the condition: the point in 1 Expression value is null with: error message in the first branch and without Condition in the second it does not work.

If I use the status of PL/SQL with: ERRMSG is null, it does not work.

The strange thing is: if I change the logic to
1. If the message ERROR IS null - branch to Page 7
It DOES not work with the value of the point in 1 Expression is NULL.

So my question is: can someone explain? Or tell me the difference between the terms?
