“Year to year” in OPAC search produces parsing error

• Article Type: General
• Product: Aleph
• Product Version: 21

Desired Outcome Goal:
Performing a "Year to year"-search using the certain year fields on the extended search page produces a parsing error, with the year variables jumping in to other fields. How to avoid this?

Procedure:
The "Year to year" search is not setup correctly. Instead of setting in $alephe_root/www_f_lng/find-a-xxx01 ...
<input type="hidden" size=4 name=find_code value="WPY">
<input size=4 name=request value="$0600">
<input type="hidden" size=4 name=request_op value="->">
&nbsp;to&nbsp;&nbsp;&nbsp;
<input size=4 name=request value="$0600"><br>
... use $alephe_root/www_f_lng/find-include-filter for the "Year to year" search.

Currently there is the standard index code WYR in this table and not your index code WPY.
