After been in for 60 lines of code I saved the script (save as). when I got to 100 lines I clicked save (because it already was 'saved as' previously) and it did not save the extra code from after the first save as..
to get it to update the file I 'saved as', I had to click 'save as' again because it did not do it when clicking the 'save' button following a 'save as' ..
hope you get what I mean sounds better in my head lol...
anyways got there in the end, just dont want anyone loosing there code if there writing a lot of it... lol would be a disaster.. lol
