Could you specify which "baby mats" you're talking about?
And if it's some that are supposed to have function (the baby mat originally from the EA store), then do you have Apartment life or Mansion & Garden? Those are needed for those baby toys to work.
If it's a forum-type site, you've downloaded from, you might get better help there, especially if the creator is available.
Also, please remember that all words don't start with capital (big) letters. Perhaps in German, but not in English. It's very tiring for the eyes (It feels as if there is a full stop after each word), and in any case there's no need to prematurely retire your shift-keys.
Excerpt from the site rules:
No leet/text speak - eg: Lets c whu cn m@ke teh most complic@ted l33t spek ev@rr is not acceptable. A lot of users here have English as a second language and have a hard enough time understanding as it is. To that end, please make an effort to use proper grammar and spelling. We don't expect everyone to have perfect textbook English, but the clearer you are, the better you will be understood, and the more response you'll get to help questions, or any post in general. We are not the grammar police here and understand typos happen and not everyone is a perfect speller, but if you're not using periods, commas, capital letters and a reasonable semblance of accurate spelling out of pure laziness, we will call you on it.
While we're on the subject of punctuation, etc, please do not type in all caps. It's bad forum etiquette and viewed as shouting.
