Did anyone used the function “Array contains element”, as for me, it seems to have a little bug.
If I have only numbers in the array and I try to find a number it doesn’t work, the moment I add also a letter, it works … but I only if I want to find letters … and I don’t need letters 
Some suggestions or can we report this little bug ?
I’ve created only a demo app to show you this

Hola!
Yes, there is a problem but when the array is created by a Make Array or Split Text column.
Instead by using a Lookup, everything works perfectly:
here the case using a Split Text column. the plugin fails…
Saludos!
but lookup uses the values in a single column and I need the values from multiple columns.
I think the approach is different and I can’t get those to in a column, as the values are assign in a row … So, this isn’t a solution for me… but thanks for the help.
do you know if this could be fixed in the next period ?
I know it’s not the solution for you, don’t worry 
It’s just a help for @SantiagoPerez in order to cover all cases with this bug.
Saludos!
The engineering team is working on a fix for this. Thanks for reporting it.
