Amount Values are numbers, but not Costs

I'm attempting to use payment form for a site that is selling certain quantities of items for certain prices.

When I do
VALUES:
345 items ($300)
862 items ($600)
1,400 items ($1,000)
etc

AND
FEES
300
600
1000

PMForm adds the quantity to the fee and I get wrong amounts ($645).

So I tried switching the order:
VALUES:
$300 for 345 items
$600 for 862 items
$1,000 for 1,400 items
etc

NO FEE

This worked fine until we get up over 1,000. The client wants the commented formatting, but it breaks the value and I get amount due: $1.

Is there any way (without hacking the code, which I can certainly do) to force PMform to treat the values as a string and just use the fees?

=> This issue is something which I fixed long time ago and should not happend now. Could you please let me know what version of extension you are using ? Are you using 1.6 version ?
