Okay, thank you.
Please remember to search the dogs name (only) first.
Look carefully at the list that pops up (W.E.'s Gage was already there as N2W's Gage, for example.)
If you see Gage already there, then just select that dog who becomes the sire to whatever dog you're entering.
If it's not there, then enter the full name of the dog, which will conduct a second search, then enter.
I deleted the extra dogs and you're back in.
