you can probably predict what is going on here

Something you should know: lerping ScreenGuis is gratuitous

Use TweenSize!

1TextBox.Focused:connect(function()
2    local targetSize = UDim2.new(XSize,0,0,3);
3    Frame:TweenSize(targetSize,"InOut","Linear",.2);
4    repeat wait() until Frame.Size == targetSize;
5end)

Sometimes this happens mightydifferent 85 — 8y

When using lerp, I like to make functions so it's easier to do.

I made a simple function that goes through a table and lerps to whatever color is next;

01function hb(num) --This function is just a Hearbeat:wait(); it makes the lerp smooth
02    if num == 0 or num == nil then
03        game:GetService("RunService").Heartbeat:wait()
04    else
05        for i = 0,num do
06            game:GetService("RunService").Heartbeat:wait()
07        end
08    end
09end
10 
11function llerp(gui,Table,timeToNextFrame,alpha,hbWait)
12    spawn(function() --This is so you can run other code while the llerp function is being ran
13        local Frame = 1 --Starting at table[1]
14        for t = 1,#Table,1 do --Looping through the table
15            print("TABLE: "..t) --This will print where the function is in the table
16            if Frame > #Table then print'Done' break else Frame = Frame + 1 end --Checking if it is done going through the table, and if it isn't adds 1 to table
17                for i = 0,1,alpha do --Alpha is the amount of times it will loop to get to 1. (.1 will be 10, .01 will be 100)
18                    gui.BackgroundColor3 = gui.BackgroundColor3:lerp(Table[t],i) --Doing the lerp
19                    hbWait = hbWait or 0 --If hbWait is nil, it will be 0
20                    hb(hbWait) --Smooth waiting
21                end
22            wait(timeToNextFrame) --This is how long it will wait until lerping to the next color
23        end
24    end)
25end
26 
27local colors = {
28    Color3.new(1,0,0); --Red
29    Color3.new(0,1,0); --Green
30    Color3.new(0,0,1); --Blue
31    Color3.new(1,1,1); --White
32    Color3.new(0,0,0) --Black
33}
34 
35--And finally, calling the function
36llerp(script.Parent,colors,.5,.01,.01)
37----Where the GUI is, the table for the colors, the time it takes to go to the next color, the amount of times it will loop to get to 1 (smaller numbers = smoother lerp), and the heartbeat:wait() (smaller numbers also = smoother lerp)

As for the Frame's size, simply use TweenSize;

`1`	`Frame.Size:TweenSize(UDim2.new(XSize),0,0,3),` `"Out",` `"Sine")`
