I am programming a FIP that display an image when the temperature of the cabin is an specific range. I can program the image to be visible when the temp is higher than a value and also when is lower than another value, but i cannot do both at the same time. I can do this:

 <Visible> (L: CabinTemp, celsius) 27.5 &gt;= </Visible>

Or this:

<Visible> (L: CabinTemp, celsius) 35 &lt; </Visible>

 

But the programme does not work if I try

 

<Visible> (L: CabinTemp, celsius) 27.5 &gt;=  AND (L: CabinTemp, celsius) 35 &lt;</Visible>

<Visible> (L: CabinTemp, celsius) 27.5 &gt;=  (L: CabinTemp, celsius) 35 &lt; AND</Visible>

<Visible> (L: CabinTemp, celsius) 27.5 &gt;=  AND 35 &lt;</Visible>

<Visible> (L: CabinTemp, celsius) 27.5 &gt;=  35 &lt; AND</Visible>

 

I tryed all those posibilities and none works. As soon as i try any of those lines, the image is there all the time, without restrictions. What amd I doing wrong?

Is the use of different variables (CabinTempPAST vs CabinTemp) intentional?

It was a typo when I was copy pasting from original into the post. That is not the issue. Both vars are the same. One reads the value one second before the other, so it knows if the temp is going up or down, but it does not matter wich of the two I use. When I was copy pasting the code to post it here I took it from two diferent files, but it is the same. I have just corrected it the original post so is clear.

RPN uses Postfix notation, the operator comes after the operands, not between them - and all RPN operators are lower case in AAO - please check the tables in the AAO manual. All commands and operators must be written exactly as they are printed there, including upper/lower case characters.

<Visible>(L:CabinTemp, celsius) 27.5 &gt;=  (L:CabinTemp, celsius) 35 &lt; and</Visible>

Take special care with the space characters, they are among the most critical thing that can go wrong. There is no space between L: and the variable name, but there is one after the comma. And there must be exactly one between all operands, operators and commands.

I would suggest that you try the code in the RPN Editor in AAO first, with the debug window open. Then, copy and paste the code from the LOWER textbox, the grey one, where you can see the compiled code - this removes the "dots" and replaces them with spaces.

Thak you for the response. I think the problem is the case of the operator. i was aware operators come after the operands, but tt was a bit of despertion. Thanks also for the suggestion of using the RPN edittor in AAO, i do not know how does it work, but I will give it a try. All these is very new to me and i have very basic notions in programming (a bit of actionscript 2 and some java for beginners, that's all) Thanks again.

 

IT WORKED!!! It was the lower/upper case thing. Also, thanks to checking the documentation i have managed to find out it is possible to align text left or right with with <HorizontalAlign>right</HorizontalAlign/>. Very useful. Thanks.

PS. I cannot work out how can I use the RPN editor to text my code. I will keep trying and reading.
