Variable Time Duration

[amir_kourani]

Is there a way to assign the timer duration at runtime (not in the process diagram). i have tried to put the value of the time duration to a variable and added this variable at the start of the process but exception is raised when the process reach the timer.

The value in duration can resolve to a variable, just make sure the variable is a string and is a valid duration. What exception was raised?
