Is there any error in my function?

here is my code:

Function loadNewEtnaXMLFail
MessageBox MB_RETRYCANCEL "Load new Etna XML data failed!" IDRETRY retry IDCANCEL stop
stop:
MessageBox MB_OK "show stop"
Quit
retry:
MessageBox MB_OK "show retry"
Call loadNewEtnaXML
FunctionEnd

when i press the retry button,i see the messagebox "show retry",then the finish page will show,the "loadNewEtnaXML"function have not been called.why?
thank you

But you can debug it yourself:

1) Use MessageBox command to verify the result of variables, like:

MessageBox MB_OK $0 

Will show the variable $0 in a message box.

OR

2) To use the code below you need the plugin "DumpState" which can be found on the Archive.

DumpState::Debug 

It will show all the common variables ($0-9, $R0-9, $INSTDIR, $LANGUAGE, $OUTDIR, $EXEDIR, $CMDLINE) and the stack, and you can change them all by clicking over them on the dialog box. It's recommended if want accurate details.

thank you very much,i got it😁
