filter record in Page og Report

Hi I have a problem.

I want to ad a variable to a page/report where I can set a filter on a record I will use for processing some code.

Problem is that when I create a variable datatype text, ad it to page request and set table relation to the table in question (e.g. resource table), each time i lookup for a new number it replaces my previous value with the new selected one.

In this way i am not able to make a filter expression like:

100100..100200

Because after writing 100100.. and want to select my next criteria result is 100200

Hope you can understand my problem...

Best regards,

Michael
