Email synax: messeage depending on the value of a group value

[cgn]

Sending emails with my W4K is working. Once a day, I'd like to send an email. The message should depend on the vealue of the group values. This message should be list, of all values, which are below a certain limit - in this case 85. I tried the following code - synax error. Any idea? 

Code:

for i = 0, 30, 1 do
  SP = grp.getvalue('35/1/' ..i)
  if (SP < 85) then
    message = 'Alert: ' '35/1/' ..i '<br>'

end
end

end
end

...missing string concat after Alert: string...

Code:

for i = 0, 30, 1 do
  SP = grp.getvalue('35/1/' .. i)
  if (SP < 85) then
    message = 'Alert: ' .. '35/1/' .. i '<br>'
  end
end

'35/1/' ..i '<br>' Must be '35/1/' .. i .. '<br>'

Corrected version that will alert all objects that are below the threshold instead of only one:

Code:

message = ''

for i = 0, 30 do
  addr = '35/1/' .. i
  value = grp.getvalue(addr)
  
  if value < 85 then
    message = message .. 'Alert: ' .. addr .. ' = ' .. value .. '<br>\n'
  end
end

if message == '' then
  message = 'OK'
end
