Hello :icon_neutral:
I am doing a test to return payment details - but seem to be having a problem with the card number. When I run the code below I get an error saying that it is too large or small to be an integer.
If I make the variable a float the info is returned but it is a silly number with decimal point and plus signs in it !
Is there an obvious way around this please - or am I doing something else wrong:-/
Thank you ... John.

m_CardNumber = int.Parse(txtCardNumber.Text);
m_StartDate = txtStartDate.Text;

m_SecurityCode = int.Parse(txtSecurityCode.Text);
DateTime startDate = DateTime.Parse(txtStartDate.Text);
DateTime endDate = DateTime.Parse(txtEndDate.Text);
try
{
if (string.IsNullOrEmpty(txtNameOnCard.Text)) //if (txtNameOnCard.Text == string.Empty)
