Resource Info Fields

Hi,

I have two questions regarding Resource Info questions in the Service Catalog function.

1) We designed a Service Catalog Service Request and for some reason one of the Resource Info questions doesn't appear when its submitted. When you complete the form it's all fine, but when it appears in our queue it's blank and if you change it manually it stays blank! The other questions are fine. Would it be advised to delete it and recreate it ?

2) Can the custom script be used to hide options on a dropdown within Resource Info ? i'd to add a script that if someone chooses a department, they get a list of options based on their specific department.I thought if I had one large list...I could simple say if you're in this department hide all but the ones I need. I tried this, which works for fields, not Resource Info questions. Any ideas ?
$CS.removeOptions("Resource Info Q1",["Option 1"]);

Thanks
