Macro editing

Hello Experts,

I am novice in Macro, guru kvsrinivasamurthy has solved brilliantly for similar set of numbers.
Now I am using new set of different but less numbers. I have tried unsuccessfully replacing numbers suggested by kvsrinivasamurthy. ( you may may see details under my name Karnik , solved )

Use only 2,4,6,8, numbers to get single digit, two digit, three digit , four digit possibilities
Goal seeking Results:-
single digit output :-, 2,4,6,8,
Double digit out put :- 24,26,28,46,48,68,22,44,66,88,
Few three digit examples: 246,248,468,,222,444,666,888 and so on....
Please see attached Excel 2007 file, currently I do manually that is prone for may omissions,
Thanks in advance
Karnik

Hello HSV and Jacobshavn
Thanks for looking in to my issue, both Macros works, but basic criteria is missing, which is in a row, second digit cannot be smaller than first, e.g. 2,4 is fine but not 4,2 for three digit 2,4,6, if fine but not 4,2,6, or 4,6,2
So two digit possible outputs are only 24,26,28,46,48,68,22,44,66,88 and not 42,64,84..... etc.
I am novice to Macros, I am unable to edit/modify !
Thanks
