# “schematic -->” in answers with multiple CircuitLab schematics

First time I noticed this bug, I though I may had made a typo, but now I spot the same bug again.

As someone may edit out the bug, this is what it looks like in the editor pane. Notice the stray "schematic -->" about half way:

<!-- Begin schematic: In order to preserve an editable schematic, please

<!-- End schematic -->

$R_{ab} = R_{an} + R_{bn} + \frac{ R_{an} × R_{bn} }{ R_{cn} }$


Basic rules to calculate the equivalent resistance of a resistor circuit

I think it happens when you edit a circuit diagram in an article with multiple circuits.

At the same time part of the answer text vanishes, but I edited that back in again (2nd time too):

allel resistors: $R_P = \frac{1}{\frac{1}{R_3}+\frac{1}{R_4}}$
