Revert: None of 3.5.4 scripts work in 3.6

[oldedit]

I had vB upgade me. Went fine, but then, I get notice that 36 templates need to be reverted. After some questionning, learn that you revert and then paste your custom scripts back in the templates and save.

But when I do that, I get a database error 1064. vB technical support says have to change code and to come here for help. I didn't write the scripts and can't fix them, unless there is a common element that screws them up. I pasted two of them into the Mac Texteditor so they wouldn't be corrupted by Word. Then I stopped reverting until I can get help one way or another.

Ideas? :help: If you can get me ideas, I have a consultant who knows php, but not vB.
