Error while Compile. Please Help!

I am developing a VB application using ActiveX EXE, everthing is okay and well functioning, but don't know what happened yester day my program has an error that I can't solve it. the error message is as below:

run_time error-2147217833 (80040e57)
[microsoft][ODBC SQL Server Driver][SQL server]
String or binary Data would be truncated.

when I debug they highlighted the code as below:

oConn.BeginTrans
FundCode = txtFundCtgy & "-" & txtFundCode & "-"

For I = 1 To MSFlex.Rows - 2

amt = 0 - MSFlex.TextMatrix(I, 5)
sqltext = "INSERT INTO Acc_GL (Acc_Code,Description,Amount,Ref_1,Ref_2,Acc_Date,KeyIn_Date,KeyIn_By)" & _
"VALUES ('" & FundCode + MSFlex.TextMatrix(I, 0) & "','" & MSFlex.TextMatrix(I, 3) & "','" & amt & "','" & MSFlex.TextMatrix(I, 1) & "','" & MSFlex.TextMatrix(I, 2) & "','" & DTAcc.Value & "','" & SysDate & "','" & strUserID & "')"

oConn.Execute sqltext
UpdateTB DTAcc.Value, FundCode + MSFlex.TextMatrix(I, 0), amt

Next
oConn.CommitTrans


Please help me, because my program have been delay for 3 days already.

truncated means cut-short, so "String or binary Data would be truncated. " means that a String or Binary field is smaller than the data you are trying to put into it.

check the length of the fields, then the length of the data you are trying to put into them - for at least one of the fields you are putting in too many characters ;)
