OK, I know how to do the coding behind it.
So first you have a global number, which starts on 0
And a blank text box
Then add a new event
System>Every X Seconds set that to 1
Add action
System>Add to set that to 1
Then add a new event
System>Every Tick
Add a action
Text>Set Text then the name of your global variable with out the ""
Then thats it, Good luck!
