visible property of objects

[Wiliam-Michael]

Simple question:

I have a button and a text (Tostop the carnage press the Stop button)I want these 2 objects to be invisible first and then either to fade in or to jsut be visible after playing the carnage for 10 seconds 
So I typed in ACtions
Keyframe 1.
stop_btn.visible = false;
stop_txt.visible = false;

Keyframe at the end of the frames where the "carnage"happens:

count ++

If (count == 300){
stop_btn.visible = false;
stop_txt.visible = false;
}
(The idea is to let the user see the carnage for 10 seconds and then give him a chance to press "Stop" to end it.

But the ábove' did not work at all - it brought out a strange error message after compiling. 
I finally changed the setup so that the button always shows.
But for future experiments - how would an expert solve this problem?

Kind regards, William-Michael

Sorry It should, of course, read 

count ++

If (count == 300){
stop_btn.visible = true;
stop_txt.visible = true;
}

One further question 
I continually keep losing my stage. And no no CTRl +Z will get it back.
Is there not any method to get it back - I mean Window is filled with panels - but there is no entry saying "stage".
Kind regards,

OK - re. the losing of the "stage"'  - I think you have to just continually try to move panels apart - so may be this is how you find a "lost atage".

So there's an error message, that presumably tells you exactly what the problem is, but you're going to ignore it and you're not going to tell us what it is.

Hi Clay.

Interesting skull.
Well the message for turning a button instance  on an off was:
Scene 1, Layer 'actions', Frame 1, Line 20, Column 4 1050: Cannot assign to a non-reference value.
Scene 1, Layer 'actions', Frame 1, Line 9, Column 2 1050: Cannot assign to a non-reference value.

One further question:
Why is it that using a motion tweeen on the same keyframe blocks buttons and user input into textboxes ?

And the lines of code that the error messages were calling out is WHAT, exactly?

Hi Clay,

If it is the motion tweenyou are referring to - there is no error message - the error is that the buttons are just blocked - the same is valid for the input textfield: you cannot put the cursor into it. 

If it is button instances - they are single lines like   go_btn.visible = false/true;
