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.

Only the first Main used is the one where all scripts should be attached to so if you have scripts from level 2, transfer them to level 1 and just make sure your level jumps are in the rifgt order.
When running as one scenario, combine all scripts into a Master script (add includes from other levels)

The GS engine only runs one script. So if you have attached another one in the second level, but you start your game with the first and come then into the second one, there won't be any script or main loaded then.
