Variable user-inputs are not valid in MetaStock Explorations.
Try this for your Exploration filter:
---8<--------------------------------------
{ http://www.metastocktools.com/#metastock }
{ References 'Linear Regression Trendline' indicator }
{ Minimum Trendline/bar cross count }
minCount:=2;
{ Lin Reg Trendline reference }
trend:=Fml("Linear Regression Trendline");
{ Trendline/bar cross count }
crs:=trend>=L AND trend<=H;
crossCount:=BarsSince(crs AND Ref(crs,-1)=0)+1;
validCrossCount:=If(crs,crossCount,0);
{ Filter signal }
validCrossCount>=minCount
