UDF - Find Consecutive Numbers In Single Cell With Dash

I need find consecutive Numbers in a singles Cell but each numbers have a leading zero and "-" (Dash)

My problem is that the UDF that i found on this forum, is for numbers with out leading zero with comma ",",

So even if change the "," by "-", still getting a error Because the Code is designed to Read numbers Formats different than mine..

My Numbers are located in Cell G12 (down), and the message that i need to show in the cell result is :

If Found :
0 Consecutives --> 0
2 Consecutives --> 2
3 consecutives --> 3
4 consecutives --> 4
5 consecutives --> 5
2 Set of consecutives --> 2S

Example of 0 consecutives --> 01-04-07-12-25-30
Example of 2 consecutives --> 01-02-07-12-25-30
Example of 3 consecutives --> 01-02-03-12-25-30
Example of 4 consecutives --> 01-02-03-04-25-30
Example of 5 consecutives --> 01-02-03-04-05-30
Example of 2 sets of consecutive s --> 01-02-07-12-25-26

BTW my numbers start on Cell G12 down..
