  Hi,

  I'm not sure what exactly is going on here, but your experimental sequence is a little messed up. The variable Statement appears in the variable list, but is defined in a source (block_loop_1), that itself doesn't really exist, or at least only as a ghost. There is a slim chance that you can get rid of ghost items, by emptying out the unused items. So give it a try. If the problem still persists, the most straightforward way to fix it, is to start over building your experiment. Probably it will be fine, if you just copy over all the sequences from the current version into a fresh experiment, but in case the problem persists, try to create all items from scratch. In any case, you probably won't be happy continuing with the current script.

  Also, the variable does in fact not exist! So, even if you can fix the issues with the structure, you will have to make sure that you define the variables that are needed to present on the sketchpad.

  Good luck,

  Eduard
