BSP document.forms[0] undefined

Hi,

In the view attached below for attachments, if no file is added then submit action should not happen. This is handled in the OnClientClick event of "AttachAdd" button which in turn calls the isFileLoaded function.

The document.forms[0].<%= controller->gc_document_path %>.value is always throwing error. I also tried document.getElementById('<%= controller->gc_document_path %>')

No form tag is used here. Can any one help me regarding this? The view is attached below for reference.

Thanks & Regards

G.Raja
