adjust data before sending

I have a dropdown, and I need to change the value of it before sending to insightly or it won’t match insightly choices. Particularly this dropdown gets price added to the value and I have to remove it before sending to Insightly.

Is there some syntax options for custom value? There’s only 2 choices in the dropdown so and ifelse or case structure would work.

I am comfortable writing a filter if you can tell me the names of the filter to use.

thanks,

Ryan
