@abacogirl1993 It's best to take the excellent advice igazor gave you over on the Sims forums—go to Edit Town, evict your sims, copy the apartment building to the bin, bulldoze the lot, replace it with the bin copy, and move your sims back in. If you do all of this in one Edit Town session, without saving your sims to the bin, the sims will keep their jobs and relationships but lose their promised dreams and opportunities.
Thanks @puzzlezaddict unfortunately it didn't work
@abacogirl1993 I'm not much of a builder myself and have never built an apartment building, so I can only tell you so much. But it would be useful to know what happens if you place this modified apartment in a brand-new save and moved a family in. The new save will be free of any corruption that might exist in the old one, and the same is true for the sims. Then you could try moving the room markers around and changing out the doors, as mentioned in the Sims forums thread.
If you report back on the results of your tests, even if nothing works, it will help narrow down the source of the problem.
@puzzlezaddict thanks for that unfortunately that didn't work either. I switched to an existing family in the game and tries to have them enter the building and that didn't work
I'm not that much of a builder either and I should probably mention I do not see any room markers
Also I didn't bud the building it was an existing one from the game
@abacogirl1993 There are several adjustments you'd need to make to a community lot to make it into a functioning apartment. Here's one thread on the subject, with a linked tutorial; you can find plenty of others just by googling.

I still think it would be a good idea to create a new save where you could experiment with tweaking this building. Once it works in the new save, you can copy the lot to the bin and transfer it back into your existing save.
@abacogirl1993 Then it sounds like you need to replace the doors with something else. The trick of bulldozing and replacing the lot would have deleted any leftover action jigs blocking the doors, so the problem has to be the doors themselves. With apartment buildings, there are different kinds of doors (e.g. NPC doors that your active sims can't use), so you need to be careful in selecting which to use. Again, testing this in a new save is better than messing around with your existing sims.
I have no problem opening the thread I linked above; maybe try using a private browser window. Or you can choose any of the links I found with this google search:
