# if statement not working

I am trying to make a sage interactive that switches between dx dy and dy dx. Yet, in my interactive when I press either I see no difference in the latex generated ie the order dx dy or dy dx does not chnage

```
def interplay(order= permutations,function= input_box(sin(x*y)),lower_x_bound= input_box(0),upper_x_bound = input_box(1),lower_y_bound=input_box(0),upper_y_bound=input_box(1),showGraph = checkbox(default = False)):
try:
if permutations == "dx dy":
result = integral(integral(function,x,lower_x_bound,upper_x_bound),y,lower_y_bound,upper_y_bound)#function.integrate(x,lower_x_bound,upper_x_bound).integrate(y,lower_y_bound,upper_y_bound)
q="$\int_%s^{%s} \int_%s^%s %s \,dx\,dy = %s $" % (lower_y_bound, upper_y_bound,lower_x_bound,upper_x_bound,function,result)
# puts expressions inside latex
else:
result = integral(integral(function,y,lower_y_bound,upper_y_bound),y,lower_x_bound,upper_x_bound)
#actually calculates integral
q="$\int_%s^{%s} \int_%s^%s %s \,dy\,dx = %s $" % (lower_x_bound,upper_x_bound,lower_y_bound,upper_y_bound,function,result)
```
