disable window

Hello,
I try to deactivate a field text (Field 3), when I click a button radio (Field 4), then to reactivate it with another button radio (Field 2).
The problem with my code it's because the field is deactivated well if I go to the following page then if I return.
My code:

Function LeaveCustom 

ReadINIStr $0 "$PLUGINSDIR\raccourci.ini" "Settings" "State" 

StrCmp $0 "0" bouton_continuer 

StrCmp $0 "2" radio_oui 

StrCmp $0 "4" radio_non 

Abort 



radio_oui: 

GetDlgItem $1 $hwnd 1203 

EnableWindow $1 1 

WriteINIStr "$PLUGINSDIR\raccourci.ini" "Field 3" "Flags" "ENABLED" 

Abort 



radio_non: 

GetDlgItem $1 $hwnd 1203 

EnableWindow $1 0 

WriteINIStr "$PLUGINSDIR\raccourci.ini" "Field 3" "Flags" "DISABLED" 

Abort 



bouton_continuer: 

FunctionEnd

Thank you,

If you want to deal with "Field 3", shouldn't you use GetDlgItem $1 $hwnd 1202?

"ENABLED" is not a control flag. You should use "" instead.
