hi.when I use CVODE from neuron main menu Tools/variablestepcontrol
this error comes:

near line 105
{isvar()}

CVode[0].active1 )

Assuming that you are

1. developing this model
2. proceeding in an incremental fashion
3. have been saving your revisions as you go along

then the key to diagnosing the problem is to examine the change that was made between
the "last good version" and the current version that generates the error message. So what
was that change?
