HELP. ProgressBar problem

[Cocodrilo]

Here i have a variable "ttime" which is used to define seconds, in this case. I calculate the 1% of the variable "ttime" to add to the progressBar every second.

The problem is this: If my variable "ttime" is <= 100 everything works fine, but when "ttime" > 100 , the progressBar just don't increases. I've noticed that when the "value" variable's result is 0.5, 0.58, 0.9, anything between 0 and 1 this happens.

is there any solution? or some other way to do this?
