I'm trying to create an equation which includes a sequence enclosed with vertical lines (cardinality) but where the left hand line is preceded by a subscript indicator. There's no problem with a trailing subscript indicator but a subscript in that position has a different meaning in this context.

Can anyone suggest how OOMath might be persuaded not to consider the leading "_" as an error?

_2 widehat left none lline %phi%psi rline right none

Any help much appreciated.

For subscripts on the left, try with lsub:
Code:
A lsub b

In your case:
Code:
{left lline sequence right rline }lsub{index}

FWIW, I don't know the 1st thing about complex formulas but just playing with this one:
{widehat left none lline %phi%psi rline right none}lsub 2
to see the differents effects I seem to have generated the same thing with this shorter one:
{widehat lline %phi%psi rline}lsub 2

At least it seems to be the same alhtough "left none" & "right none" may have some subtle effect that I'm missing.

Definitively, friday I was asleep:
Code:

{widehat left lline %phi%psi right rline}lsub 2

The "none" command is not necessary... Embarassed
