Where is the autopaginate tag coming from? As the error message
states, the view that is throwing the error is called ReportIMH, not
IRSerNum. Presumably the pagination links are taking you to a
different view, which is throwing a ValueError for some reason. Maybe
you should look at that view - or, if you're not supposed to be going
to that view, work out why autopaginate is taking you there.
