Action Buttom -> Calculate

{OBSNOW("Weight") / ( OBSNOW("Height") * OBSNOW("Height") ) * 703}

observations are stored as strings, try this to convert the strings to values

{val(OBSNOW("Weight")) / ( val(OBSNOW("Height")) * val(OBSNOW("Height")) ) * 703}

or you could use this function

{fn CalcBMIConv(heightnow,heightprev,weightnow) {
local heightval = ""

cond
case heightnow <> ""
heightval = heightnow
case heightprev <> ""
heightval = heightprev
else
heightval = ""
endcond

if weightnow == "" or heightval == "" or val(weightnow) == 0 or val(heightval) == 0 then
return ""
endif

if heightval == 0 then
return str(0)
endif

return str((weightnow / 2.2) / ((heightval / 39.4)^2))

}}

I know this is answered already but here's a shorter version that is setup in the whiteboard area...

{fn CalcBMI(){

   IF (OBSNOW("WEIGHT") == "" OR OBSNOW("HEIGHT") == "") THEN
      return ""
   ENDIF

return round((OBSNOW("WEIGHT") / 2.2046) / ((OBSNOW("HEIGHT") / 39.3701) ^2),2)
}}
