I’m trying to create an expression to set a value for a property tag  
the first line works but the second causes an error.

if({Madera/TF2\_Controller/TANK801}\>{Madera/TF2\_Controller/TANK801Hsp},1,0)  
if({Madera/TF2\_Controller/TANK801}\<{Madera/TF2\_Controller/TANK801Lsp},2,0)

You have to nest them, you can’t have two separate if statements in an expression. So it would be like this:

`if({Madera/TF2_Controller/TANK801}>{Madera/TF2_Controller/TANK801Hsp},
1,
if({Madera/TF2_Controller/TANK801}<{Madera/TF2_Controller/TANK801Lsp},
2,
0))`

Picky thing this script. I typed it as it looked but I may have had a space wrong. I copied it and pasted it and it worked.

Thanks, Now to figure out how to do indirect tags for popup chart.

I have 4 tags SP, HL, LL, Temp
