Duplicate output destination error

Hi ALL,

I am trying to send the value from 2 or more check boxes to the same field in
a database. In Dreamweaver, Insert Record,if you were to choose the same column
for different check boxes(form elements) & then when you hit submit on the form
after uploading it ,you get this error message "

Microsoft JET Database Engine error '80040e14'

Duplicate output destination 'FlowAnalysisID'

..... line 115 (which in the code is MM_editCmd.Execute)."

Any suggestions please.

Arun
