Hey community -
When I use integrals in my math equations, Lyx wont produce a preview for me.

From the log I get the following message:

Code: Select all

! LaTeX Error: Command \iint already defined.
               Or name \end... illegal, see p.192 of the manual.

But what do I do to solve this?

Please produce a minimal working example.

Regarding your problem: It seems like the command \iint is already defined in youe preamble, if I am not mistaken.

Ah my preamble defined it, and my math options did it too... unchecked boxes in options, and it works fine
