for _,btns in pairs(script.Parent:GetChildren()) do
    if btns:IsA("ImageButton") then
        btns.MouseButton1Click:Connect(function()
            if table.find(example ,btns.Name) then --stops working here
                local info = table.find(example ,btns.Name)

When answering, if your answer does not fully solve the question, it should be written as a comment to the question instead of as an answer.

use the key, not the index.

print(info.1) -- which should actually be info[1]

should be

print(info["ex1"])

Tables are split into two components: the array component, and the hash-table (dictionary) component. Arrays are defined by ascending numerical indices.

table.find will perform a search through the array component by ascending through its indices, however, as example is entirely a dictionary, that search will quickly cease. The key-value pairs you desire are also not directly within example.

The correct code is:

local info = example.Example[btn.Name]
if info then
    -- Use 'info' ...
end

The information at example.Example[btn.Name] is also a string, so writing info.1 does not make sense. The syntax itself is illegal.

It seems like you need to read up on tables.
