If you're gonna use loops, use 2 loops
<cfloop index="j" list="Qty,Main,Block">
<cfloop index="i" from=1 to=6>
<cfinput name="#j##i#">
</cfloop>
</cfloop>
Seeing as the fields are dynamic, you can read them using Evaluate();
<cfloop index="j" list="Qty,Main,Block">
<cfloop index="i" from=1 to=6>
<cfif Evaluate("#j##i#") is "">
This field is empty
</cfif>
</cfloop>
</cfloop>
Or to set this field to be something;
<cfset "#j##i#"=myValue>
Variable name flexibility is a wonderful thing
