Or Statement Not Working

I've made this script to adjust the extensions on our rectangular transition ducts but it doesn't want to work for me. Everything is fine if I keep it simple and leave out the " Or "Ductmate 35" " part but for this to work, I will need the or statement.

Anyways, here's the script...

select item.cid
case 2

	dim extin = item.dim[6].numvalue
	dim extout = item.dim[7].numvalue
	dim con1 = item.connector[1].value
	dim con2 = item.connector[2].value
	
	if ( con1 = ("TDC" or "Ductmate 35") ) and
	(extin < 2 ) then
	item.dim[6].value = 2
	end if

	if ( con2 = ("TDC" or "Ductmate 35") ) and
	(extout < 2 ) then
	item.dim[7].value = 2
	end if

	if ( con1 <> ("TDC" or "Ductmate 35") ) and
	(extin < 0.5 ) then
	item.dim[6].value = 0.5
	end if

	if ( con2 <> ("TDC" or "Ductmate 35") ) and
	(extout < 0.5 ) then
	item.dim[7].value = 0.5
	end if

	item.update()

end select

Can anyone spot the problem? I'm hoping its an embarrassingly simple one.

In lisp you would need another pair of brakets I think its the same here if ((.........

Do you mean it should look something like this?

if ( con1 = ("TDC" or "Ductmate 35") ) and
[color="red"]((extin < 2 ))[/color] then
item.dim[6].value = 2
end if

I don't think putting something into two sets of brackets ((X)) would change the logic of the statement. I tried it just to be safe and there was no change.

Thanks for trying though

Dont program with this type of code method try this

if (( con1 = ("TDC" or "Ductmate 35") ) and [color=red](extin < 2 ))[/color] then

Thanks for the tip. That actually looks a lot better and I changed my script to use the same format. Unfortunately it didn't fix the problem, but I think I figured out what is happening.

take a look at these two pieces of code...

if ( con2 = ("TDC" or "Ductmate 35") ) and
	(extout < 2 ) then
	item.dim[7].value = 2
	end if

;;;which is followed by...

if ( con2 <> ("TDC" or "Ductmate 35") ) and
	(extout < 0.5 ) then
	item.dim[7].value = 0.5
	end if

I think that the or statement may be working, but then I have a second line of code which is supposed to handle what happens if con2 does not equal TDC or Ductmate 35. I didn't take into account that this statement would be true whether the connector were TDC or Ductmate 35 because it can't be both. I probalby should of made that into an "and" statement.

Still, that would take a slightly chunkier piece of code. Do you know how I could use an else statement for this? I tried a few variations but kept getting errors I couldn't understand/fix.

This is what my script now looks like...

select item.cid
case 2

	dim extin = item.dim[6].numvalue
	dim extout = item.dim[7].numvalue
	dim con1 = item.connector[1].value
	dim con2 = item.connector[2].value
	
	if (( con1 = ("TDC" or "Ductmate 35")) and (extin < 2 )) then
	item.dim[6].numvalue = 2 elseif
	extin < 0.5 then
	item.dim[6].numvalue = 0.5
	end if

	if (( con2 = ("TDC" or "Ductmate 35")) and (extout < 2 )) then
	item.dim[7].numvalue = 2 elseif
	extout < 0.5 then
	item.dim[7].numvalue = 0.5
	end if


	item.update()

end select

Can you spot any syntax errors in that last script?

By the way, thanks for all of your help so far.
