Specifying a parameter on index

Hi, I have defined a variable x(i,j) and sets i and j. However i want
to let j equal to some parameter m, which I define as a scalar and
give a value. When I type x(i,m), i get an error.
Any help will be appreciated.

Thank you

You can use the Ord operator
Depending where you are using it the syntax may vary but below there is an
example

X(i,j)$(Ord(j) eq m)
