Change form

[spectura77]

There is a complete on schedule dialogue box in change form is not working as expected when changed is completed it should be true .this issue is happening Intermittent 

I have checked  there is a business rule which runs and its conditions are

status changes from work in progress,

planned date change is not empty 

actual end is not empty

task count is 0

and also there is a script written on business rule -

current.u_compliance = true;

current.update();

All this conditions seems to be correct but still its not working please guide
