Want to trigger a function from a certain frame

Hi this is my first post. I'm sure my problem is simple but I've been looking all over the forums and the internet for the answer with no luck. So...

I really just want to know how to trigger a function when my movie hits a certain frame.

I made a very simple flash show to try to illustrate my problem a little more clearly. I have a green and a gray button. Using the 'switch_buttons' command I turned the gray button invisible at the beginning. What I then want to happen is that on the 10th frame the green button will become invisible and the gray button will appear. But I haven't had any luck. It seems like I need to call a function to switch the buttons somehow.

I am just getting into coding with Flash and would really appreciate any help. I have attached my flash file to the post if you would like to look at it.

Thank you in advance.

You can place the function call in the frame where you want the action.

Or try this:

PHP Code:

---

onEnterFrame = function () {
    if (_currentframe == 30) {
        your_function_name();
    }
}; 


---

Thanks ilike2,

I'll give it a try.
