Dear Klaow,
You now that R is case-sensitive? That is, see the following:
# Set
interven <- "pzq"
# Then
interven=="pzq" # provides
[1] TRUE
# However,
interven=="PZQ" # provides
[1] FALSE
That is, you have to spell the values in the code exactly as spelled in the data set.
Best,
Gerta

Dear Klaow
Without your data it is hard to be sure. I assume you have checked that
the variable interven does indeed contain some values "PZQ"?
