Check Every value with your DataBase Columns Data type.Use Debugging for checking values.
And use NULL for empty column(if allows).

As the error suggests, one of the values that you are passing into the sql is not of a valid type e.g. you may be passing in string for a number type datafield in the database.

Don't build your SQL query like you do ; better create a SqlCommand object, and add SqlParameters to it.

For example :

C#

string commandText = "INSERT INTO wbtrans VALUES(@recId, @termCode2)"

using (SqlConnexion cnx = new SqlConnection(connectionString))
using (SqlCommand cmd = new SqlCommand(commandText, cnx))
{
   cnx.Open();
   cmd.Parameters.AddWithValue("@recId", int.Parse(lblRecID.Text));
   cmd.Parameters.AddWithValue("@termCode2", cboTermCode2.Text);
   int result = cmd.ExecuteNonQuery();
}

I didn't put all the fields, but the scheme is the same.
I assumed recId id an integer, and termCode2 is a string. You have to pass the correct field type when you assign your parameters values.

Edited: forgot to open the connection
