ARRAYFORMULA not expanding - google-sheets

Question

I have the following ARRAYFORMULA entered into cell D2, and it seems like it should be expanding downward throughout the entire column (I'll do the "check for blank A2" addition to the formula once this part works correctly), but nothing is expanding. Where have I gone astray?
Here's the formula:
=ArrayFormula(IFERROR(QUERY('Form Responses 1'!$A:$J,"select count(E) where (C contains '"& $A2:A &"' or C contains '"& $B2:B &"') and (E) Contains 'Option' label count(E) ''"),0)+
IFERROR(QUERY('Form Responses 1'!$A:$J,"select count(F) where (C contains '"& $A2:A &"' or C contains '"& $B2:B &"') and (F) Contains 'Option' label count(F) ''"),0)+
IFERROR(QUERY('Form Responses 1'!$A:$J,"select count(G) where (C contains '"& $A2:A &"' or C contains '"& $B2:B &"') and (G) Contains 'Option' label count(G) ''"),0)+
IFERROR(QUERY('Form Responses 1'!$A:$J,"select count(H) where (C contains '"& $A2:A &"' or C contains '"& $B2:B &"') and (H) Contains 'Option' label count(H) ''"),0)+
IFERROR(QUERY('Form Responses 1'!$A:$J,"select count(I) where (C contains '"& $A2:A &"' or C contains '"& $B2:B &"') and (I) Contains 'Option' label count(I) ''"),0))

try:
=ARRAYFORMULA(IF(TRIM(B2:B)="",,IFNA(IFNA(VLOOKUP((B2:B),
QUERY({IFNA(IFNA(REGEXEXTRACT('Form Responses 1'!C2:C, "\b"&TEXTJOIN("\b|\b", 1, (B2:B))&"\b"),
REGEXEXTRACT('Form Responses 1'!C2:C, "\b"&TEXTJOIN("\b|\b", 1, TRIM(A2:A))&"\b"))),
MMULT(N(REGEXMATCH('Form Responses 1'!E2:I, "(?i)Option")), {1;1;1;1;1})},
"select Col1,sum(Col2) where Col1 is not null group by Col1 label sum(Col2)''"), 2, 0), VLOOKUP(TRIM(A2:A),
QUERY({IFNA(IFNA(REGEXEXTRACT('Form Responses 1'!C2:C, "\b"&TEXTJOIN("\b|\b", 1, (B2:B))&"\b"),
REGEXEXTRACT('Form Responses 1'!C2:C, "\b"&TEXTJOIN("\b|\b", 1, TRIM(A2:A))&"\b"))),
MMULT(N(REGEXMATCH('Form Responses 1'!E2:I, "(?i)Option")), {1;1;1;1;1})},
"select Col1,sum(Col2) where Col1 is not null group by Col1 label sum(Col2)''"), 2, 0)), 0)))
UPDATE:
=ARRAYFORMULA(IF(C2:C="",,IFNA(IFNA(VLOOKUP(B2:B, QUERY({TRIM(FLATTEN(QUERY(TRANSPOSE(
REGEXEXTRACT('Form Responses 1'!C2:C, TEXTJOIN("|", 1, "("&SUBSTITUTE(TRIM(UNIQUE(
FILTER({Sheet3!B2:B; Sheet3!A2:A}, {Sheet3!B2:B; Sheet3!A2:A}<>""))), " ", ").+(")&")"))),,9^9))) ,
MMULT(N(REGEXMATCH('Form Responses 1'!E2:I, "(?i)Option")), {1;1;1;1;1})},
"select Col1,sum(Col2) where Col1 is not null group by Col1 label sum(Col2)''"), 2, 0),
VLOOKUP(A2:A, QUERY({TRIM(FLATTEN(QUERY(TRANSPOSE(
REGEXEXTRACT('Form Responses 1'!C2:C, TEXTJOIN("|", 1, "("&SUBSTITUTE(TRIM(UNIQUE(
FILTER({Sheet3!B2:B; Sheet3!A2:A}, {Sheet3!B2:B; Sheet3!A2:A}<>""))), " ", ").+(")&")"))),,9^9))) ,
MMULT(N(REGEXMATCH('Form Responses 1'!E2:I, "(?i)Option")), {1;1;1;1;1})},
"select Col1,sum(Col2) where Col1 is not null group by Col1 label sum(Col2)''"), 2, 0)), 0)))
