[R] Integration with variable bounds

If this is posted elsewhere I cannot find it.  I need to perform multiple
integration where some of the variables are in the bounds of the other
variables.  I was trying to use R2Cuba function but cannot set the upper and
lower bounds.  My code so far is :

int <- function(y){
u2 = y[1]
z2 = y[2]
u1 =y[3]
z1 = y[4]

ff <- u1*(z1-u1)*u2*(z2-u2)*exp(-0.027*(12-z2))

1e-12,flags= list(verbose=2, final=0))

I know that code is wrong but it shows that variables are in both the upper
and lower bounds.
