Paint a button at a specific time interval

[Lion]

I need the button color to change at a specific time. What am I doing wrong?

[Salman_Dev]

have you tried downloading the app and testing the app on your cellphone?

And you have to change this block :

With this :

Or

does not work.

I would like to know if you are using any extension because few of the blocks you have used are not from the blocks which are already in App Inventor.

@Mayank_Kumar

The OP has created a procedure called TimeBetween, using the procedure block.

[Mayank_Kumar]

Oh OK, I mistook it to be something else

[TIMAI2]

Try with numbers (although it should make any difference. These blocks, slightly different, but they work for me

[Mayank_Kumar]

I guess this method would use the minimum number blocks. Check It Out!

[TIMAI2]

erm, uses more blocks than the OP's example, and less "efficient", also, probably doesn't work, because the format time will not equal a number

[Mayank_Kumar]

What does that mean? I didn't get it.

[TIMAI2]

It is better now you have changed the time format to hours

[Lion]

Thanks. Works. This is what I needed.

[Mayank_Kumar]

Oh yes, I by mistake used the wrong block but I updated it a minute later.

[Lion]

Thanks. Good.
