Change default value on a field per unique landing pages

forms

#1

Hi,

There is a form that shares multiple landing pages. And, for each landing page sharing that form, we would like to change the default value to match the content of the landing page - making each default value unique to each landing page. How could we change that menu (“Product Interest”) to have a unique default value appear for each shared landing page (http://info.helmerinc.com/centrifuge-contact-us)?

I’ve noticed that the ID’s on the input / select tags change on every refresh or visit of the page, therefore, making it challenging to use JavaScript for this task. Do you have any suggestions as to how to go about selecting a different default value for this field?
