How to print custom form field values in thank you

Hello,

I have three campaigns and each have unique custom form fields. I need to customize the thank you message for each campaign and print values from the custom fields. Campaign 2 has check boxes that allow someone to designate where their gift goes. I see that if i add the name of the field: [SELECT_A_PROGRAM] the value prints in the email but it has [" "].
Example:
Thank you for donating to ["the arts"]
or
Thank you for donating to

How do I get rid of the brackets and quotes?

I would also like to know if I can suppress a field form printing in the email or thank you page if it has no content. I am comfortable working with php is it would require modifying a file.

Thank you for your help.

Hi

Yes. You can. Just use the correct syntax [NAME_OF_CUSTOM_FIELD_IN_UPPER_CASE]

For example, if you have a custom field named jd_donation_description, you can use the text [JD_DONATION_DESCRIPTION] and it should work well
