How do I get a radio button in 1 group to be checked when a radio button in another group becomes checked?  
For example: I want the button in var1 w/value “No voice” to become automatically selected when button var2 w/value “$39.99” is selected.  
\<input type=“radio” name=“var1” value="$39.99 More" checked=“checked”\>  
\<input type=“radio” name=“var1” value=“No voice”\>  
\<input type=“radio” name=“var2” value="$29.99" checked=“checked”\>  
\<input type=“radio” name=“var2” value="$39.99"\>

Is using if/else statements the right way? Would I also create more php if/else statements for other radio button scenarios?  
Thanks for any help on this.
