I did added validation for those variables in the map file, but for some reason I am getting the below error. msValidateParameter(): Regular expression error. Parameter pattern validation failed. msEvalRegex(): Regular expression error. String failed expression test. msValidateParameter(): Regular expression error. Parameter pattern validation failed. Could anyone help me with where I am wrong? Below is the map file content for this layer. All the six variables would be numbers (may be a decimal number), Is my regular expression correct? WEB VALIDATION value_one "^[\d+(\.\d)]*$" value_two "^[\d+(\.\d)]*$" value_three "[^\d+(\.\d)]*$" value_four "[^\d+(\.\d)]*$" value_five "[^\d+(\.\d)]*$" value_six "[^\d+(\.\d)]*$" END END LAYER NAME "state" TYPE polygon STATUS ON CONNECTIONTYPE POSTGIS CONNECTION "user=postgres password=****** dbname=shpdb host=localhost port=5432" DATA "the_geom FROM (SELECT gid, the_geom, totpop1 FROM state_shape) AS SUBQUERY using unique gid" PROCESSING "CLOSE_CONNECTION=DEFER" CLASSITEM "totpop1" OPACITY 100 CLASS EXPRESSION ([TOTPOP1] >= %value_one% AND [TOTPOP1] < %value_two%) STYLE COLOR 255 108 118 OUTLINECOLOR 255 255 255 END END CLASS EXPRESSION ([TOTPOP1] >= %value_two% AND [TOTPOP1] < %value_three%) STYLE COLOR 254 189 75 OUTLINECOLOR 255 255 255 END END CLASS EXPRESSION ([TOTPOP1] >= %value_three% AND [TOTPOP1] < %value_four%) STYLE COLOR 254 247 46 OUTLINECOLOR 255 255 255 END END CLASS EXPRESSION ([TOTPOP1] >= %value_four% AND [TOTPOP1] < %value_five%) STYLE COLOR 39 251 114 OUTLINECOLOR 255 255 255 END END CLASS EXPRESSION ([TOTPOP1] >= %value_five% AND [TOTPOP1] <= %value_six%) STYLE COLOR 108 111 205 OUTLINECOLOR 255 255 255 END END END -- Regards, Prabu Raja
