Remove comma from passing values to gateway.

[bluebeachdesign]

Under cost_1 there is a comma being passed to a gateway when the price is over 1k.
In the store edit area under currency display there are no commas being used.

The current format is: 10,000.00

The format needed is: 10000.00

How do I solve this issue?

Example:
<input type="hidden" name="1_cost" value="1,182.00" />
Should be
<input type="hidden" name="1_cost" value="1182.00" />
