Search for a range

I need your help please.  


My search "Not Range" is not pulling my data.
and if I enter in the textbox G2002 or G2001-G2004
Record #1 will not come up.
the search will only get the first range but not the second one.


if the user enter in the GroupTxt : G2001  
output record:
RuleDetailID                       ConditionAttributesAndValues

1                                           <br> IF Px Between Range (H0000 - H9999)&nbsp;<br> AND Px Between Range (G2000 - G5000)

                                             Range (F01-F99) <br> AND Px Between Range (G2000 - G5000)


if the user enter in the GroupTxt : Not G2001
