[mapserver-users] Expressions

[Fawcett, David]

Jay, 
 
This sounds like more of a GeoMoose problem than a MapServer problem.  I
would try that list as well.

	I am trying to do expressions based on a shapefile...I had this
working in a prior version but now it wont work...

	 

	The fields GEO_SIMPLE and dateValues exist in the shapefile.

	I have the date values in "dateValues" as TEXT, 8 characters.

	 

	The Star symbols come up but the application freezes up and wont
draw the rest of the layers...so I have something wrong...

	 

	Does the date format have to be changed?

	Does the field have to be a date field?

	Will the below format work?  ("%2M%2D%2Y)

	                But in the field it looks like this 11509

	 

	If I remove the param types and the expression stuff it draws
the layer fine...so it has to be with the dates.

	 

	THANKS IN ADVANCE FOR ANY HELP

	 

	I get this error:

	 

	Strfdate is not defined

	 

	mapParams[i].SetAttribute('value',strfdate(new
Date(d.getTime()+offset),formats............
