Hi,

I am new to Mathematica and I have been stuck with this seemingly small issue for some time now - 

x:=.5;

g = Manipulate[
  Plot[Sin[i t], {t, 0, 10}, 
   ImageSize -> Scaled[x]], {i, 1, 5}]

I want to assign the variable x to .5 and then use it in Manipulate function, which plot a graph of sin[i t] and imagesize should be scaled to x( which is already assigned). But when I am deploying this in cdf, I am having this error 

"The specified setting for the option GraphicsBoxOptions, ImageSize cannot be used."
