I'm getting this error

error 035: argument type mismatch (argument 1)

From this line of my code

GetCmdArg(1, text, sizeof(text))

Text is set a few lines up on this line

decl String:text[255]

I honestly can't see what the problem is, this is a mod of an existing plugin which appears to have ceased development and I just need a little extra functionality for it to make my job easier, I've copied GetCmdArg from lower down in the code, changed the given values but this is still what I get

Any Ideas or do I need to supply more code
