        MessageBox.Show("Enter Contact Number.", Me.Text, MessageBoxButtons.OK, MessageBoxIcon.Information)
        Exit Sub
    End If
    If ComboBox1.Text.Trim.Length = 0 Then

It could be the data type of some of your database fields. For instance you have fields called months, days, years ,age, etc. These could be defined as type Integer. If that is the case then you need to leave out the single quotes in your statement:

sqlCommand = "INSERT INTO Personss (names, months, days, years) VALUES ('" & txtbname.Text & "', " & cmbMonth.Text & ", " & cmbDay.Text & ", " & cmbYear.Text & ")"

Also, if you have a date type the single quotes need to be replaced with #. For example.
sqlCommand = "INSERT INTO Personss (date) VALUES (#" & dateValue.Text & "#)"

Hope this helps!

The trouble with posting

sqlCommand = "INSERT INTO Personss (names, contactnumero, emailadds, pages, projects, agents, sources, months, days, years, times, agents1, transactions, months1, days1, years1, times1, agents2, transactions1, months2, days2, years2, times2, agents3, months3, days3, years3, remarks, months4, days4, years5, remarks1, months5, days5, years5, remarks2 ) VALUES ('" & txtbname.Text & "', '" & txtContact.Text & "', '" & txtEmail.Text & "','" & txtWeb.Text & "', '" & ComboBox2.Text & "', '" & ComboBox1.Text & "', '" & ComboBox44.Text & "', '" & cmbMonth.Text & "', '" & cmbDay.Text & "', '" & cmbYear.Text & "', '" & cmbYearTime.Text & "', '" & Combobox4.Text & "' , '" & ComboBox10.Text & "' , '" & cmbMonth1.Text & "' , '" & cmbDay1.Text & "' , '" & cmbYear1.Text & "' , '" & cmbYearTime2.Text & "' , '" & ComboBox5.Text & "' , '" & ComboBox11.Text & "' , '" & cmbMonth2.Text & "' , '" & cmbDay2.Text & "' , '" & cmbYear2.Text & "', '" & cmbYearTime3.Text & "', '" & cmbMonth3.Text & "', '" & cmbDay3.Text & "', '" & cmbYear3.Text & "', '" & TextBox2.Text & "', '" & cmbMonth4.Text & "', '" & cmbDay4.Text & "', '" & cmbYear4.Text & "', '" & TextBox3.Text & "', '" & cmbMonth5.Text & "', '" & cmdDay5.Text & "','" & cmbYear5.Text & "' , '" & TextBox4.Text & "')"

and asking "where is the syntax error" is that without knowing the values of all of the controls you are patching in, it is impossible to know what the actual query is. It may be a mismatched quote but I am certainly not going to wade through multiple lines of concatenations to determine if a quote is mismatched or misused. I've responded to dozens of SQL query questions with "you should be using parameterized queries". That would make your code easier to read and debug. At the very least if you had done

sqlCommand = "INSERT INTO Personss (names, contactnumero, emailadds, pages, projects, agents, sources, months, days, years, times, agents1, transactions, months1, days1, years1, times1, agents2, transactions1, months2, days2, years2, times2, agents3, months3, days3, years3, remarks, months4, days4, years5, remarks1, months5, days5, years5, remarks2 ) VALUES ('" & txtbname.Text & "', '" & txtContact.Text & "', '" & txtEmail.Text & "','" & txtWeb.Text & "', '" & ComboBox2.Text & "', '" & ComboBox1.Text & "', '" & ComboBox44.Text & "', '" & cmbMonth.Text & "', '" & cmbDay.Text & "', '" & cmbYear.Text & "', '" & cmbYearTime.Text & "', '" & Combobox4.Text & "' , '" & ComboBox10.Text & "' , '" & cmbMonth1.Text & "' , '" & cmbDay1.Text & "' , '" & cmbYear1.Text & "' , '" & cmbYearTime2.Text & "' , '" & ComboBox5.Text & "' , '" & ComboBox11.Text & "' , '" & cmbMonth2.Text & "' , '" & cmbDay2.Text & "' , '" & cmbYear2.Text & "', '" & cmbYearTime3.Text & "', '" & cmbMonth3.Text & "', '" & cmbDay3.Text & "', '" & cmbYear3.Text & "', '" & TextBox2.Text & "', '" & cmbMonth4.Text & "', '" & cmbDay4.Text & "', '" & cmbYear4.Text & "', '" & TextBox3.Text & "', '" & cmbMonth5.Text & "', '" & cmdDay5.Text & "','" & cmbYear5.Text & "' , '" & TextBox4.Text & "')"

Debug.WriteLine(sqlCommand)

then posted the output we would have had a reasonable chance to spot the error. However, even seeing that would not tell us if a field is mismatched to the underlying type of a particular column.
