Newbie help -- can't get this to work

Two problems ...

1. Cannot figure out how to restrict to U.S. stocks. I have been trying this
Keep :[SI Country]="United States"
It looks like this leaves me with no stocks passing the filter.

2. I keep getting an error on [SI Depreciation 12m]. I tried [SI DEP_12M] as well and that throws an error. Both are show up as missing fields.

re problem 1 searching

re problem 1

searching through some screens (jobs) suggests you just need to remove the space:

Keep :[SI Country]="UnitedStates"

the following is also how i've also seen it done:

Keep :[SI ADR/ADS Stock]="F"

the latter is usually followed or preceded by removing OTC (unlisted) stocks:

Keep :[SI Exchange]<>"O"
