Three LEDs control by one momentary switch

Three LEDs control by one momentary switch.
The Spec:
1/ Hold the switch Red LED on, other two LEDs Green & Blue off.
2/ Click the switch toggles LEDs Green & Blue on, LED Red off.

Below two Sketches work fine! One sketch toggles LEDs Green & Blue light by momentary short click, other sketch lights up LED Red, other LED off by long hold; Short click LED Red off, other LED on .

Third one was combined two sketches. It does meet Spec 1/, but does not toggle LEDs Green & Blue. Can someone help to fix so both specs are met?

Thank you for your attention, Your help is greatly appreciated!!

Welcome to the Forum. Please read these two posts:

How to use this forum - please read. and
Read this before posting a programming question ...
You may also find useful information that would answer your question here:
Useful links - check here for reference posts / tutorials

You have posted code without using code tags. The code tags make the code look

like this

when posting source code files. It makes it easier to read, and can be copied with a single mouse click. Also, if you don't do it, some of the character sequences in the code can be misinterpred by the forum code as italics or funny emoticons.
If you have already posted without using code tags, open your message and select "modify" from the pull down menu labelled, "More", at the lower left corner of the message. Highlight your code by selecting it (it turns blue), and then click on the "</>" icon at the upper left hand corner. Click on the "Save" button. Code tags can also be inserted manually in the forum text using the code and /code metatags.

Unless the sketch is too large, it's better if you post your code, rather than attach it. When it's attached, we have to download it, create a folder then open your code in our IDE. And afterwards, the folder remains unless we navigate to the "Temp" folder and manually remove it. It's much easier to just view the code in your post.

I don't see where you allowed for switch contact bounce.

try to remember the state when the button is pressed, like

[code]

val =digitalRead(buttonPin);

if(val==HIGH && old_val==LOW)
{
  state=state+1;
delay(10);

}

old_val=val;

if(state==1)
{
  digitalWrite(pinLed,HIGH);
}

[/code]

Two sketches #2 & #3 work fine.
Combined these two code to the sketch#3, it is missing the functions as #2
Thank you again
