Can't show equation tag properly

begin{align*}
sum_{j=1}^{m_0-1},(-1)^{j-1}hspace{-3ex}
sum_{substack{ k_{m_0 +1} leq k_{m_0} leq cdots leq k_{j+2} leq k_1 leq boldsymbol{ell} \ k_2 < cdots < k_j < k_{j+1} leq k_1 }}

boldsymbol{ell}, } tag(3) label{eq:3}
end{align*}
which is very close to our goal, equation eqref{eq:2}.
Comparing equation eqref{eq:3} with equation eqref{eq:2}, we discover that both have the identical 1ts{st} through $(m_0 -2)$ts{th} terms ($1 leq j leq m_0-2$).
The only difference of the two is that the $(m_0 -1)$ts{th} term in equation eqref{eq:3} is ...
end{document}


I try to put a tag next to the equation, but the result comes out as:



enter image description here



The tag is not displayed correctly. Also, the eqref{eq:3} are displayed in the same, wrong way. (I omit the code having eq:2 and eq:1.)

    Welcome to TeX.SE! Replace tag(3) by tag{3} (curly brackets around 3). Otherwise LaTeX thinks you mean tag{(}.

tag{<tag>} takes a mandatory argument. If you don't supply the surrounding braces, then it takes the next token as the argument.



In your case, tag(3) doesn't use the suggested format tag{<tag>}, so it turns into tag{(}3), numbering the equation with ( and leaving 3) in the input stream. You're looking for tag{3}:



enter image description here



documentclass{article}

usepackage{amsmath,amssymb}

begin{document}

begin{align*}
sum_{j = 1}^{m_0 - 1},(-1)^{j - 1}hspace{-3ex}
sum_{
substack
{ k_{m_0 + 1} leq k_{m_0} leq cdots leq k_{j + 2} leq k_1 leq boldsymbol{ell} \
k_2 < cdots < k_j < k_{j+1} leq k_1
}
}
= sum_{ k_{m_0 + 1} leq k_{m_0} leq cdots leq k_2 leq k_1 leq boldsymbol{ell} }, tag{3} label{eq:3}
end{align*}
which is very close to our goal, equation~(2). Comparing equation~eqref{eq:3} with equation~(2), we discover that both have the identical
1textsuperscript{st} through $(m_0 - 2)$textsuperscript{th} terms ($1 leq j leq m_0 - 2$). The only difference of the two is that the
$(m_0 - 1)$textsuperscript{th} term in equation eqref{eq:3} is ldots
