[Tex/LaTex] Missing $ inserted while adding resizebox

math-modescaling

This is probably a noob error. I get a "Missing $ inserted" error when compiling the following code:

\item $%
\begin{array}{c}
w_{M}>w_{F} \\ 
\text{or }w_{F}>w_{M}%
\end{array}%
:\left\{ 
\resizebox{6.3cm}{!}{%
\begin{array}{l}
\text{the one earning more will continue working, } \\ 
\text{whilst the one earning less will} \\
\text{go on if }w>\eta \text{, otherwise he/she }\\
\text{will drop out and provide homecare}%
\end{array}%
}
\right. $

I tried to solve it by adding $ signs anywhere I though it would be correct, but I was not able to get rid of the error. I also tried removing all $. Nevertheless, if I skip this error while compiling, the result is precisely the one I wanted.

EDIT: Thank you. It turns out I was using resizebox in the wrong way. The right code is 

\item $
\begin{array}{c}
w_{M}>w_{F} \\ 
\text{or }w_{F}>w_{M}%
\end{array}%
:\left\{ 
\resizebox{6.3cm}{!}{%
$
\begin{array}{l}
\text{the one earning more will continue working, } \\ 
\text{whilst the one earning less will} \\
\text{go on if }w>\eta \text{, otherwise he/she }\\
\text{will drop out and provide homecare}%
\end{array}%
$
}
\right. $

Best Answer

It looks like \resizebox can't be used in maths mode. Try this:

\item $%
\begin{array}{c}
w_{M}>w_{F} \\ 
\text{or }w_{F}>w_{M}%
\end{array}$
\resizebox{6.3cm}{!}{
$:\left\{
\begin{array}{l}
\text{the one earning more will continue working, } \\ 
\text{whilst the one earning less will} \\
\text{go on if }w>\eta \text{, otherwise he/she }\\
\text{will drop out and provide homecare}%
\end{array}%
\right. $
}
