Inconsistent Units in boolean Yes/No formula not working

[revitworkbench]

hello I have been using formulas to calculate boolean outputs for years, however now in t 2018 it appears that it is not working?? What the heck happened? What am I doing wrong? Thanks

Just type

"Tier 2_4D Unistrut" in the formula box, no need for "if... 1, 0"

@revitworkbench or you need [Tier 2_4D Unistrut] in this format inside the formula.

Hello @revitworkbench,

I agree with @Secttor and @ToanDN.

In your case, you need only to put the parameter Tier 2_4D Unistrut in the formula.

But if you want to use an IF statement in a boolean parameter YES/NO parameter, just do the following:

IF (<condition>, <result-if-true>, <result-if-false>)

for YES/NO parameter:

IF (<condition>, 1=1, 1=0)
