IDW Interpolation-Syntax Error in parsing grid expression

Discussion created by darais on May 14, 2010
I keep on getting two error messages during IDW interpolation for certain data sets.  One is SYNTAX ERROR IN PARSING GRID EXPRESSION and the other is SYNTAX ERROR AT OR NEAR SYMBOL SPACES.  Does it have something to do with the title of the shapefile?  Or with how many data points you have?  Any feedback would be greatly appreciated!  thanks!
