You could add '|| 0' to the Template code, wherever it does a numeric operation. That may be quite a few places... That would cover the case where the value is blank... but not other non-numeric values, like trying to add 1 to 'sheep'. Another alternative would be adding a function to replace all non-numeric values with zero, and use that instead of '|| 0'. Of course, this would all require getting to know the code inside the Template modules. FWIW, I agree with your point that Template itself should avoid these warnings on behalf of the template authors. It already does so for undefined values, so non-numerics seems like a natural extension of that idea. Here's an example of that function to replace non-numerics. The regex may need some tuning: sub replace_non_numeric { my ( $val ) = @_; if ( $val !~ /^-?\d*[.e]?\d+$/ ) { $val = 0; } $val; } > Travis Basevi wrote: > > Er, yeah, I'm fully aware of that.
