Solved Attempt to call method 'GetComponent' (a string value)

I am sometimes getting an error when calling this function:

Code:

local takeDamage = character:GetComponent("TakeDamage")

The error is attempt to call method 'GetComponent' (a string value):

How would i go about checking if GetComponent is a string or not before i call the method?

 

Check if character is nil of course.

 

I did but it still messes up sometimes. I found a workaround anyway. SOLVED.
