We provide services to various counties and the price varies by county. I need help setting a Javascript so that when they choose the county, the correct price is automatically populated into the price field for totals.

The dropdown list is formatted as follows:

County1,46
County2,55
County3,75
County4,100-150
County5,46

where County1 is the name of the County and 46 is the dollar amount that they will be charged.

I've seen the function where I can split an array, but I can't figure out how to make this work with data in a dropdown list. I'm also not sure if that would work since I have some counties with variable prices, like County4 in the list above.

I also need the script so that everytime they change the dropdown list, the total field is automatically updated. I understand that can be down with an ONCHANGE script.

I'm looking for help specifically as it relates to RSForms!Pro so that I can just plug the script into the "Additional Attributes" box...not wanting to edit the HTML that RSForms!Pro automatically creates for me.

Any help would be greatly appreciated.
