[mjau]

local vch = getElementHealth ( getElementData(player,"Car")

Returns false.

Im not sure what you are trying to do but getElementData returns a string with data. while getElementHealth needs a vehicle element to work.

[DiSaMe]

getElementData returns whatever was set, not necessarily a string. If it returns a boolean, it means either a boolean was set or there was no value set at all.
