TIMER

Good Morning

I would like to know how to use a timer in my macro.

ex (I have a start button, when started it needs to create a random number in a text box every 00:05 seconds)

I can make it create the numbers, but I can not get it to update the text box automatically at the given time.

I want to have to click only once on start and the macro generates numbers until I click stop

If someone can help me, I thank them
