check values in if/else

Hello,
I have a problem in performing an if/else with two variables. IÂ´m new in this and I donÂ´t how to this.
HereÂ´s my code. I read the values of the two variables $Play and $Install, both are checkboxes. If nothing is selected a message box should appear. If $Play is selected the installer quit and the game will be started. If $Install is selected I will continue with the installer.

!insertmacro MUI_INSTALLOPTIONS_READ $Play "test.ini" "Field 4" "State"
!insertmacro MUI_INSTALLOPTIONS_READ $Install "test.ini" "Field 5" "State"
 ${If} $Play == 0 && $Install == 0
 # message box appears
 MessageBox MB_OK "Please select...!"
 ${Else} {If} $Play == 1
 # start game and quit installer 
 Exec "test.exe"
 Quit
 #${Else}{If}$Install == 1
 # go to next page installer?????
 ${EndIf}

Can you please help me with this if/else. How can I ask for values of two variables, I canÂ´t use "&&". I donÂ´t know how to do. What command can I use to continue with the installer.
Thank you very much.

Try:



${If} $Play == 0

${AndIf} $Install == 0 

   # message box appears 

   MessageBox MB_OK "Please select...!" 

${ElseIf} $Play == 1 

   # start game and quit installer 

   Exec "test.exe" 

   Quit 

${EndIf}

IÂ´ve tried this and it works. Thanks. But I have another question. If the user donÂ´t make a choice the message box appears. Now the user press the ok button and the next page of the installer appears. How can I stay on the first side so that the user can make his choice???

You need to add an abort call right after your message box call.

How can I do an abort call? IÂ´m not familiar enough with this syntax. Could you please help me?

See in blue below:



${If} $Play == 0

${AndIf} $Install == 0 

   # message box appears 

   MessageBox MB_OK "Please select...!" 

   abort

${ElseIf} $Play == 1 

   # start game and quit installer 

   Exec "test.exe" 

   Quit 

${EndIf}

This is examplained in the help files, Section 4.5.3:

The leave-function allows you to force the user to stay on the current page using Abort
