Hello,
There isn't much for me to say here but I'm pretty sure this would be an easy task since the problem looks simple.
Allow me to take a look at it first, identify the bug and you'll only have to chose me afterwards. I'll then proceed to fixing it and you can pay me after I finish.
I know what I'm doing and I'm good at it, I've worked on many big projects here on Freelancer, some for 1000USD+, and got create reviews and feedback from my clients, I know I got this, let me handle it for you once and for all.
Thanks for reading,
Mario Adabachy.
