Error datatype when storing inputted variables to L1

ClrHome
Input "(",A
ClrHome
Input "("+toString(A)+", ",B
ClrHome
Disp "("+toString(A)+", "+toString(B)+")"
Input "(",C
ClrHome
Disp "("+toString(A)+", "+toString(B)+")"
Input "("+toString(C)+", ",D
ClrHome
Disp "("+toString(A)+", "+toString(B)+")"
Disp "("+toString(C)+", "+toString(D)+")"
If A=C
Then
Disp "ILLEGAL INPUT"
Disp "RESTARTING..."
Input "",Z
DelVar Z
prgmLINEEQU
End
{A,C→L₁
{B,D→L₂
LinReg(ax+b) 
Disp "Y="+Y₁

So basically, I have assigned an input into A, B, C, and D. I put 1 into A and B, and 2 into C and D, and on the lines

{A,C→L₁
{B,D→L₂

It gives me a data type error (storing matrix to list) on the variables. After trying different ideas for 30 minutes with the people on my discord server, including:

• Close curly bracket (no change)
• Using expr() incase they were strings (data type there, so it is a value)
• A[1] instead of A (syntax error on the brackets)
• [A](1,1) (same thing)
• A(1,1→A (again, syntax)

We're out of ideas so I'm turning here for help. Any ideas?

The only way to raise the error you claim to be seeing is by writing

:{[A],[C]→L₁
:{[B],[D]→L₂

where [A] - [D] are the matrix names (not just the letters surrounded by brackets) given under [2ND][Xֿ¹][NAMES]. The real variables A - D always stored just regular values, so

:{A,C→L₁
:{B,D→L₂

works just fine.

This is just something I saw that seems weird to me, but this:

Input "",Z
DelVar Z

can be much simplified into this:

pause

Also, I don't know if it would help with your issue, but does it work if you store the variables one at a time in the list? Maybe for some reason storing two breaks it? (I'm don't have my calculator right now so I can't test it.)
