Qlik Sense rename with IF works for some but not others?

[YG]

Hi All,

I am having a dilemma with renaming with IF condition and when I use with some operators (wildmatch)  with many IF conditions it works but couple of conditions it doesn't. 

Below Yellow highlighted names I want to change it to just "Failed" and "Success"

This is what I tried so far,

=if(wildmatch(event_type, 'AddPasswordSuccess'), 'Success',
     if(wildmatch(event_type, 'AddPasswordFailed'),'Failed'))

= if (event_type='AddPasswordSuccess', 'Success',
      if(event_type='AddPasswordFailed', 'Failed'))

NON of the above works,  BUT below is working for another Dimension

=if(wildmatch(channel_function,'reg-pin*'),'reg-pin',
if(wildmatch(channel_function,'reg-pwd*'),'reg-pwd'))

I dont understand how this Dimensions are similar but one works but the other. Anyone who can help would be really appreciated. Thanks in advance

Look at your replace-statement again in the expression. You have not written it correctly.

I have no Idea Why but Used the same expression before,

=if (event_type=('AddPasswordSuccess'), 'Success',
if(event_type=('AddPasswordFailed'), 'Failed'))

But wanted the fields displayed to the "Right" and it is working, But don't understand why not in bottom
