Custom "Donation Amount" field in autoresponder

I tried to pull the "Donation Amount" (a paypal field) into my email receipt, but it wouldn't just print the dollar amount (eg. "Total $200.00").  It will say: 

I can't get rid of the subheading "Description".  I created a hidden field and copied the value of the Donation field into it, so I could just pull up the dollar amount - however, that field value came up in brackets (e.g., "{200}").

Is there a way I can just pull up the number 200.00 (or whatever the user enters as their donation amount)?

Thanks very much

I fixed it by switching text state to number in your condition.

It should give you numbers only this time.
