serial # problem

Just tried to enter the 185's in the reg. and they were rejected!---(the cubs and the 154 went in)---error said numbers are NOT valid for them. what did I do wrong here?---these 2 have funky #'s on them and I never did find out what year they are.

185--------22000113U038754*
185--------2100109U042609*
154--------014035 (it entered ok)

anybody know what year these are?----- thanks; sonny

038754 = 1975
042609 = 1976
014035 = 1969

Thank you! I was trying to use too many numbers. Now I can finish the entries. Thanks again. Sonny

Now have all 6 (3 reg cubs and 3 number lo-boys) in the registry ! thanks; sonny
