Depends what you are doing
You shouldn't have any errors on default plug ins or conditions if you are using them correctly
A common one is not having the sprite you are calling not already in the layout at the start of the layout.
All the sprites and other layout objects have to be in the layout at the start. YOu can then destroy them or re use them but they have to exist at the start.
Other errors can crop up from not using arrays correctly or while loops etc, if you are using 3rd party plug ins then that is a whole different issue.
You can post a pic or details maybe someone can help
but basically if you read through the manual you should be able to use all the default plug ins and conditions without too much fuss.
