How about using the filter command?

ON mouseUp
   local tThisTown, tStatClients
   lock screen
   put value(the selectedLine) into tThisTown
   put fld "statClients" into tStatClients
   filter tStatClient with "*" & tThisTown & "*"
   put tStatClient into fld "results"
END mouseUp

The *'s at the start & end of the filter string mean that your town
can occur anywhere in the line, not just at the beginning or end.
