Second Click no response

[Jerry]

In A drop down list - linking the change event to a Javascript function which returns flas if an error exists. If teh change errors ou, the subsequent click on a drop down item produces no effect - must click on another item and then the original.

Investigation shows that the DropDownList contains a previousVALUE which is sotred after the click on the item. It appears taht this is checked on subsequent clicks and if teh same - no event is fired. I was unable to clear this value in the return form the change event.

I added an OnOpen event which clears the value and this has solved the issue.

Any recommendations on alternative approaches

Thanks

Jerry
