Hi all!
I’ve been working my in-game Police Computer (MDT).
I have it set up so that when a player utilizes the Cell Phone, they’re able to send an emergency call. When sending the emergency call, all the information goes through the server and is supposed to end up at the MDT.
The MDT has a scrolling frame named CallList, call list is supposed to update and have a text button pop up for each call and each call has a specific case number so when a player clicks the specific call, it should populate the “CallInfo” frame. The issue I’m experiencing is that even though the call is successfully made and the output shows everything going as planned, no matter what I’ve tried, the CallList doesn’t populate with the buttons for the calls. It stays empty, as if the calls can’t be translated to the MDT.
Here is my current code, if anyone could maybe check and see what I’m doing wrong? Also, I did even run my scripts through AI, trying to see if AI could figure out the issues but even when using updated scripts, nothing is popping up.
Any help would be extremely helpful. I think it could be something very small I’m overlooking.
Here is a picture of both GUIs, on the far left is where the call textbutons are supposed to populate.
Below is The CallScript (Client), MDTHandler (Sever) and most recent Output:
