I have often used this myself - so I suggest you post some actual code. 
Note that if you want the second 'option or item' to be nothing, you 
need to splice in an empty Sequence:

If[boxflg==1,something,Sequence@@{}]

Note that if you display the resultant graphic in InputForm you will be 
able to see the structure after evaluation of the IF's, and that may 
reveal the problem.
