Dynamic Dependable Dropdown Menu Problem

[ZedHead88]

Hello all!

 

First, im very new to this forum.. and i'm really liking it! Second, i'm having this problem. I created this php dropdown menu allowing a user to select a specific phone make, model, color, size, and condition. However, when i run the script i only get the two makes i initialize within the code "Apple" and "Samsung."

 

Can someone take a look at my code and see if its the issue?

 

My back end looks like so:

 

Database name: model

MODEL_ID int(11) Key - Auto increment

MAKE_ID int(11) MODEL_NAME varchar(30)

 

Database name: color

COLOR_ID int(11) Key - Auto increment

MODEL_ID int(2)

 

COLOR_NAME varchar(20)

 

 

Database name: size

SIZE_ID int(11) Key -Auto increment

COLOR_ID int(2)

SIZE_NAME varchar(40)

 

 

Database name: con

CON_ID int(11) Key -Auto increment

SIZE_ID int(2)

CON_NAME varchar(20)
