Re: [EquisMetaStock Group] Re: Dave Landry -- Linear Regression Trendline

Thanks very much, Jose.

I encounter a problem using the trendline formula as an exploration filter: 
"This function is not allowed in this type of formula." Cursor flashes 
after "equals" in pds:=Input("Linear Regression Trendline. Is there a 
simple way to fix this? I imagine that the message applies to all such 
functions.
