i have created a game with now two levels, however i have one huge problem. Individually each of the levels run fine, but when i run them together through the first level (using the levels.wdl script) a number of vital texts that i included in the second level do not appear when the player progresses to the second level. it is as though the main loop of code from the second level does not work.

?? any help would be extremely appreciated.

Every .wdl file used by the second level has to be included in the script which runs the first level.
Basicly you have to think differently:
You run one script and not a level.
The script you run loads the level etc.
Thus I recommend to have one wdl file with one main function and all the stuff included which is needed through out the whole game.
The main function simply just loads the first level and another function (called by an entity e.g.) loads the next level.
