Don't know which columns you want to count but the following should point you in the right direction using COUNTIF and wild cards.
I have not used your actual dates but inserted data that will return a different value for each condition just for the purpose of ensuring the formulas are correct.
Following Formulas that you can copy rather than in the picture.
Cell B20: =COUNTIF(B2:B17,"*/*/*-*/*/*")
Cell B21: =COUNTIF(B2:B17,"*/*/*-")
Cell B22: =COUNTIF(B2:B17,"-")
Celll B23: =COUNTIF(B2:B17,"Skipped")
Feel free to get back to me if still having problems with this.
