[Capital Cost Allowance Not Being Calculated]

The problem I'm having is this.  I put amount of acquired asset 13800 and amount of disposed asset 3000, and ufile is not calcuting the difference.  I do not see the 3000 disposed amount anywhere on t2125 form and the cca is not being calculated at all.  It leaves a zero in that box(18).  

Edit: I finally placed the 3000 disposed amount in the correct spaces to see it on form t2125 but it is still not calculating the cca. Column 18 still shows a zero.

I'm having trouble with this area as well.  The cost of additions I have added are not showing up in column 3 of form t2125.
