Did you read the error description when trying to run your VI?

It says "Formula node: Missing right paranthesis" and it shows the part of your formula that goes wrong…

 

Instead of replicating this (extra-)large Excel formula with a formula node you should create a VI using plain LabVIEW functions. It also would help to replace the Excel coordinates (like D44) by real controls with useful labels!

I found the error

I was trying to use the function to fetch the smallest value between two numbers, but it doesn't seem to support

I did the treatment outside and sent it into the formula with the value already treated

As I wrote before: use plain LabVIEW functions, like the MinMax function…

there is no 'and' function in labview formula node.

instead you might try to use '==' instead of '='

instead of 'and' try '&&'

To the OP: This is the perfect example of why you should try to use native LabVIEW primitives whenever possible.  Then there is no such thing as "syntax error".
