Execute multiple statements within an 'if' construct

I am trying to set properties of 3 textbox based on the state of a radiobutton. If the radiobutton is selected, I want the textboxes to be grayed so the user cannot enter values. My code works if I set only one textbox. However, I can't get it to change all of teh textboxes at the same time. Here is my code so far:
if (get(handles.radiobutton1 ,'Value') == get(handles.radiobutton1 ,'Max'))
set(handles.edit4,'Enable','off', 'BackgroundColor', 'gray')
set(handles.edit5,'Enable','off', 'BackgroundColor', 'gray')
set(handles.edit6,'Enable','off', 'BackgroundColor', 'gray')
else
set(handles.edit4,'Enable','on', 'BackgroundColor', 'white')
set(handles.edit5,'Enable','on', 'BackgroundColor', 'white')
set(handles.edit6,'Enable','on', 'BackgroundColor', 'white')
end
Is there a way to use "set" to apply to more than one function handle at a time? Or why I can't I have multiple statements within my "if"?
Thank you in advance!

Use either RGB triplets (e.g. [1 0 0] for red) or one of the letters abbreviated in:
doc linespec
e.g. 'r' for 'red'
ps: gray using grb triplets will have all three (R,G,B) values the same:
e.g. 24 shades of gray:
gray(24)

[1, 1, 1] is white. If your uicontrol gets grey, this is an effect of setting the Enabled property.

Actually this should work:
H = [handles.edit4, handles.edit5, handles.edit6];
if (get(handles.radiobutton1 ,'Value') == get(handles.radiobutton1 ,'Max'))
set(H, 'Enable','off', 'BackgroundColor', 'gray')
else
set(H, 'Enable','on', 'BackgroundColor', 'white')
end
But this has no substantial difference to your code. Therefore I assume, you get the same problem - what ever it might be.

Unfortunately, this behaves the same as my code above. I just read your question and looked at the error. The Matlab error had a lot of garbage in it, but it did say "Bad property value found". I changed the background color from gray to red and now it works?! However, the background color that displays is gray not red. Go figure. Any thoughts on this? Thanks for your help

No, the error message does not contain garbage. Experiences Matlab users understand the contents of the messages, therefore it is recommended to post the messages completely in this forum.
