INSERT INTO error

sqlscript = "INSERT INTO Supportcall(ID,Description,Date,Status,Operator,Action,Customer,Contact)" & " VALUES('" & txtcallnumber.Text & "','" & txtcalldescription.Text & "','" & txtdate.Text & "','" & txtstatus.Text & "','" & txtoperator.Text & "','" & txtaction.Text & "','" & cmbcustomer.Text & "','" & txtcallcontact.Text & "')"

The above script fails when called to insert some text from the form. Any thoughts?

Is it anything to do with the date field?

You only need to include single quotes around a text or date value being concatenated not for numbers. If they are all text or dates then I'm wrong but your id is probably a number? and you have single quotes around it.
If you are using SQL Server then single quotes around a date is correct but if it's Access then try #.
