Adding delay to scavenger script in Scripting

Hey UGX, i got a script from rorkes weapon pack with the scavenger script in it and the FX plays immediatly rather than waiting 2.5s. How would i fix this? i see a code for it to wait but it doesnt seem to want to... Here is the code (i know its sloppy thats how it came

but it doesnt work...
