Don't know if this helps, but the error itself is being caused by an unset marginLeft property on the .thumb class..... (when it's trying to set properties for the objects options) The objects currents properties are: width:auto height:55 marginLeft:NaN
I'm not sure if it's an error caused by something else as I only briefly looked at the exception in visual studio and you'ere using the packed jquery js file so it's pretty hard to see. this.each(function(i){for(name in options)jQuery.attr(type? this.style:this,name,jQuery.prop(this,options[name],type,i,name));});} On May 1, 8:29 am, tahooft <taho...@tiscali.nl> wrote: > O boy, forgot it was closed.
