Hello i defined a node-red subflow environment variable like this

Why I cant use math expresions like 2*1000

i.e.

is there a workaround?

Since the variable is in mseg i'd prefer for clarity use 15 * 60 * 1000 for a 15 minute delay
Thanks in advance

Because the input only supports numbers. It does not support arbitrary maths expressions.

In other places you could change the type to JSONata to use expressions like that, but as that is normally evaluated in the context of a message being handled by a node, it doesn't fit the environment variable module where they are evaluated at the point in time the flows are started.
