    Call LoadItmxPreSumOfLoc(rs, strDept)
    
err:
    MsgBox err.Number
End Sub

I was facing a problem at the line of code i highlighted, when i debugging until the highlighted code the err.number show me 9. Furthermore, if i do not used error handle. The Project will close directly.

I'm not similar to use collection. Thus, the problem may happened in collection.

Thanks in millions for helps.
