Less than "<" working wrong way around -Solved!

[codey]

I've a very starnge problem with a script I use to control my heating. The stragest thing is that this was working perfectly, but stopped working all of a sudden.

Here is a part of my script causing me the problems



start-----------------------
'Get workshop desired temp
workshop_therm = hs.devicestring ("t14")
'get workshop current temp
workshop_current = hs.devicestring ("w5")


hs.WriteLog "workshop_current=",workshop_current
hs.WriteLog "workshop_therm=",workshop_therm
if workshop_current < workshop_therm then
hs.WriteLog "workheat","in event to cold"
'hs.WriteLog "workshop","fancoil on"
boiler = "On"
fancoil = "On"
End if
--------------------end

In the event log I get the following

21/01/2013 15:04:04 - workshop_current= - 4.5
21/01/2013 15:04:04 - workshop_therm= - 21
and it does not enter the event.

If replace the "<" sign for a great ">" sign then the script enters the if loop.

also if If change statement to be "if 4 < workshop_therm then" it also enters the loop.

any ideas whats going on?

Are you comparing strings or numbers? Try putting a CDbl() around the values before comparing. ie workshop_therm = CDbl(hs.devicestring ("t14")) Do this for both values.

Thanks Rupp that works! you star! hopefully my workshop will now warm up as 4.5c is bit chilly
