Hi Grant,
Yes, unfortunately haven’t been able to solve it as of yet. The problematic field is below.
$F{1,63-preparations.preparation.remarks}
The report is Nigerian Birds - Front, within the Birds Collection of the Tetrapods discipline. Feel free to use B000038 to test with, as it has a value in that field.
I have checked against the the Datamax Jar Labels example in Report & Label Examples to make sure that the syntax for the preparation field is the same, and can find no difference.
@NielsKlazenga apologies did not mean to ignore you! Thank you for your reply! This problem went on the backburner for a bit because I wasn’t making any progress towards a solution. I don’t think that & is the issue in this case, however that is helpful to keep in mind for the future!
