Heya,

I want to control the rate at which a timer is used, I figured I could use a slider to do this, but how to make it work? I tried this, but it doesnt work.

timer1.value = str(slider1.value)

Where are you getting the property timer1.value from and why is it a string? The timer base class has an interval property which is an integer:
timer1.interval = slider1.value
should work

I was just guessing on the .value

That .interval doesnt work either <img border="0" title="" alt="[Frown]" src="frown.gif" />

You want timer1.period=slider1.value. There is a whole section in the online reference (press Command+1 to view and search for timer)

Remember, a value of 1000 for the timer=1 second, so make sure the slider walue is going to be big enough, or steps at certain intervals. You can do this by doing some rounding.

Also remember that 32767 will be a maximum possible value, because slider maximums cannot be any higher. So using a slider may not be the best approach anyhow. But then again, I don't know what you are trying to do.
