[Mapserver-users] Zoom In to a defined area

[Jeff L.]

Hi Palle,

I tried your suggestion, but an error is posted:
loadForm(): Web application error. Not enough arguments for imgbox

Thanks

Jeff


You should name your <select> imgbox, not viewarea. Also separate your
your coordinates by +, not ,.

Best regards
