Need help with If-statements and applying units to the output in expressions.

[SidselVincents]

Hi - I'm having trouble with creating multiple if-statements in an expression. I need the expression to give a different output for three options in another property. I tried using the 'IFS' logical function, however it tells me that there is a syntax error from the beginning of the statement. What could be the cause of this? (First screenshot)

My second problem is applying  a unit to the output from an Expression. How do I solve this? (second screenshot)

Thanks in advance!

Remove the square brackets [ ] from your expression.  I don't like how the example shows this, but causes expression to fail.

IFS(Glazing Type = "3", 10, Glazing Type = "2", 100, Glazing Type = "-", 0)
