please always post a complete small document that produces the error and show the error you got.eqnarrayshould have more than one row, and each row should have two&but not doing that does not generate an error, just bad output.

@Mico... Actually for Greeks the typo is insidelambdaand not the opposite... So, it is a bug in the name... But you are right.

@Mico also it's a typo added since I posted my answer, otherwise the error I showed would be different, I'll revert :(
