Filtering via number

Hi guys,

I have created a view that displays profile information from my profile2 module. I already have some filters up and working but i can't seem to figure out how to filter by number.

Here's how it's going down, on the profile there is a field called parking spaces. Now obviously each profile has a different amount of spaces. What i need is to be able to create a filter where i can type say 60 in and it only displays users that have 60 car parking spaces or more.

Thanks.
