Get values block by block in same file

I have a file say "SAMPLE.txt" with following content,

Code:
    P1
    10,9:6/123456
    P2
    blah blah
    P1
    10,9:5/98765
    P2
    blah
    blah
    P1
    blah blah
    P2

I want a output file say "RESULT.txt" as,

Code:
    Value1:123456
    Value2:98765
    Value3:NULL

I need to first fetch content between P1 & P2 part then I want to find value of 10,9*/ which I want to save to another value. Incase some P1--P2 block doesn't contain this value I want to save it as "NULL".

How can I code the above in shell/awk ?

I am very new to scripting. Thanks for help.
