Fetch and Use not working, no error message

I need help with the following code that i have inserted in 'On user input'. All works except the last one, input.Travel1 . The only thing I can think of is that this field is of different type then the others. It is type (long) in both forms and the others are type (string) in both forms.

  1. if (input.Store_Number1  !=  null)
    {
        if (input.Store_Name  !=  null)
        {
            dat  =  Add_a_Store  [ID == input.Store_Number1];
            input.Store_Name = dat.Store_Name;
        }
        if (input.State  !=  null)
        {
            dat  =  Add_a_Store  [ID == input.Store_Number1];
            input.State = dat.State;
        }
        if (input.Zip_or_Postal  !=  null)
        {
            dat  =  Add_a_Store  [ID == input.Store_Number1];
            input.Zip_or_Postal = dat.ZIP_or_Postal;
        }
        if (input.Brand1  !=  null)
        {
            dat  =  Add_a_Store  [ID == input.Store_Number1];
            input.Brand1 = dat.Brand;
        }
        if (input.City  !=  null)
        {
            dat  =  Add_a_Store  [ID == input.Store_Number1];
            input.City = dat.City;
        }
        if (input.Travel1  !=  null)
        {
            dat  =  Add_a_Store  [ID == input.Store_Number1];
            input.Travel1 = dat.Travel2;
        }
    }
