Trying to create a complex projection based on a value chosen in an Offer user-defined field.

Summary:

In our Offer grid we have a user-defined selection list that has the following elements (N/A; 1; 2; 3; 4; 5; 6; 7; 8; 9; 10; 11; 12; 13; 14; 15; 16; 17; 18; 19). We have a requirement to export this value in a TCC export through Transitions. I am able to export the value alone just fine, but once I try to create a complex projections based off of the value I continue to get an error when running the config file. The requirements for the projections are in the content below.

Content (please ensure you mask any confidential information):

If the user selects N/A → 0 should be returned on the export

If the user selects 1-19 → 1-19 should be returned on the export (i.e. 7→ 7)
