How do I use the "contains value"-condition in the event sheet?

I would like to check if a certain string is included in an array variable.

For example: check if the name "Tom" is stored in the variable "names" (Betty, Tom, Robert,...,...)

In the event editor in "compare variable" I only find the usual = < > etc. options to compare a given value with one value stored in a variable.

What I didn't found is something like "contains". (If variable XY contains "Tom" then ...)

Maybe I looked in the wrong place?

Thanks in advance for your help :-)

... sorry for the traffic.

I found the solution by myself: I had not added the array object before.

Now I have done that and everything works fine.
