Upcoming previeuw & submitting errors

Hi, dear Simmers! I have problems at the moment with submitting sets. I get an error message that says the set that I just created is not mine! Or.. it says I must have a least 2 items into a set. Wich is very strange, because I submitted 3 or 4 different items and it keeps telling me and telling me over and over again that I do not have a set. Stupid error!! It's very strange and I don't know why this happens, because never had problems with submitting a set before. I posted my question about it at the forums, hoping that there is someone who can give me a answer. Especially because I did see that I am not the only one who gets this iritating error. Here's a previeuw of the 3 different Toony T- shirt sets for boys- and 1 Toony set with 4 outfits for Toddlers, wich I am testing in my game to shoot some pictures for a nice previeuw. There's a lot more to upcome, but we have to wait until the error problem is over. I hope it wil be very soon! Thanks for reading and your sweet attentions. I wish you all a very nice weekend! Grtz, Dirtdevill
