dom,

I'd guess that your explore is working.
 
The error msg is barking because you did not do a
GetExtraData("Issuetype") command before trying to do the
AddColumn(IssueType,"IssueType"); command.

Just try the following (exactly).

Phsst


// 1ExploreDollarVolumes
MktCap = GetExtraData("SharesFloat") * ( (O + H + L + C) / 4 ) * 1000000;
InstHldgs = GetExtraData("InstHolds");
Beta = GetExtraData("Beta");
Filter = 1;
AddColumn(Mktcap,"MktCap",12.0);
AddColumn(InstHldgs,"InstHldgs",12.0);
AddColumn(Beta,"Beta",6.2);

Phsst
