Hi,The column names I'm using often have underscores in them. I've noticed that, when writing script in the script component editor, the underscore characters mysteriously dissapear. Is this a known bug? (I can't find any reference to this by Googling)Thanks in advance,Lawrie.

Probably a bug, but also might be by design depending on where the underscores are disappearing. K

Kirk, Any underscore in a column name always disappears within the script component. Doesn't change the pipeline metadata of course and everything still works. Having said that, I've never tried using a script component that had the following columns names: Column1 Column_1 This could cause some problems!!! -Jamie
