Why isn't this camera script working?

Please can someone tell me what is wrong with this script? :( Thank you.

function onClick()
    wait(2)

repeat wait () until game.Workspace.CurrentCamera ~= nil

local c = game.Workspace.CurrentCamera
local data = LoadLibrary("RbxUtility").DecodeJSON('[{"FOV":70,"Roll":0,"c1":[249.0168762207,12.263187408447,-595.06884765625,0.99963241815567,5.2330924518174e-005,-0.027112856507301,3.6379788070917e-012,0.99999821186066,0.0019301113206893,0.02711290679872,-0.0019294018857181,0.99963057041168],"step":2.5,"f1":[249.42356872559,12.23423576355,-610.06329345703,1,0,0,0,1,0,0,0,1]},{"FOV":70,"Roll":0,"c1":[249.84315490723,18.776773452759,-660.60375976563,0.99998062849045,-0.00083417579298839,-0.0061798207461834,-5.8207667852361e-011,0.99101239442825,-0.13377061486244,0.0062358677387238,0.13376802206039,0.9909930229187],"step":2.5,"f1":[249.93585205078,20.783332824707,-675.46862792969,1,0,0,0,1,0,0,0,1]}]')
