my @VehicleProgram=('AA','BB');
#if user selects $VehicleProgram=AA

my @CrashMode=('12','13');
#if user selects $CrashMode=12

my @Load=('AA_121','AA_13','BB_12','CC_12','AA_122');

depending on $VehicleProgram and $CrashMode 
the radiobuton Load should contains only 
the relevant Values of @Load

#Radiobutton  Load (@LoadArrayRef) 
# should contain ONLY 'AA_121' and 'AA_122'

Thank you in advance for your help.
