What does the error "Amount must be between 1 and #####" mean?

The amount you're attempting to transact exceeds the single transaction limit that Constellation has set for your payment gateway account. For example, "between 1 and 200000" indicates a single transaction limit of $2000.00.

You can either post multiple, smaller payments that are within your transaction limit; or, contact Constellation Payments and request that the limit be increased.
