What you describe is not normal behavior for a value list in FileMaker Pro. Something is adding the added spaces and I can't see what from here. Please describe the design of your layout, your value list definition and any auto-enter field options you may have on the fields where you are formatting them to use this value list. This is a case where the more relevant detail that you can provide, the better.
The fields are just regular drop-downs, with the underlying table's fields formatted as number. The value list is a separate table with two fields, "Code" and "Description", with the first field stored but both displayed in the drop down.
However, I went ahead and re-did the base table for the value list and added the codes and descriptions again, and now it seems to be working. I must have accidentally added spaces after some of the entries, although it wasn't visible in the base table itself (I put it on a layout to see).
Thanks for the help!
