may do it
I made a few assumptions
- DataSetDtl.DsHdrID is not the primary key of the DataSetDtl table,
but a FK to a parent table
<!--- Form page --->
<CFQUERY name="GetPoints" dataSource="#application.DS#">
SELECT *
FROM DataSetDtl
WHERE DataSetDtl.DsHdrID = #URL.DsHdrID#
</CFQUERY>
<form name="points" action="" method="post">
<cfloop query="GetPoints">
<!--- Ouput points record --->
<input type="hidden" name="pointsPK_#GetPoints.currentRow#"
value="#GetPoints.PRIMARYKEY#" />
<input type="text" name="pointsReading_#GetPoints.currentRow#"
value="" />
</cfloop>
<input type="hidden" name="noPoints" value="#GetPoints.recordCount#">
<input type="submit" name="submit" value="sumbit" />
</form>
<!--- Action page --->
<cfloop from="1" to="#form.noPoints#" index="i">
<cfset thisPK = form["pointsPK_#i#"]>
<cfset thisReading = form["pointsReading_#i#"]>
<cfquery name="update" datsource="">
UPDATE
DataSetDtl
SET
Reading = <cfqueryparam value="#thisReading#"
cfsqltype="cf_sql_varchar">
WHERE
PRIMARYKEY = <cfqueryparam value="#thisPK#"
cfsqltype="cf_sql_integer">
</cfquery>
</cfloop>
