Google sheet Query Function Returns blank result from cell with data
I am creating a spreadsheet for my work place that will find drivers for the LED's we use but I've run into a slight problem. i pull in the data from another sheet to thin it out, i then have a sheet for formulas, one for the form, and the data on its own sheet. for some reason, i do a calculation on one sheet, then use the query function to return that result on another sheet, but the result sometimes misses data.
I am using this formula to determine how many LED's can be attached to the driver:
=IF(A4="","",IF(U4="Y",If(K4>1,IF(round(O4)=round(P4),P4&" per Channel",O4&"-"&P4&" per Channel"),IF(round(O4)=round(P4),P4,O4)),IF(U4="Min+1",If(K4>1,IF(round(O4+1)=round(P4),P4&" per Channel",(O4+1)&"-"&P4&" per Channel"),IF(round(O4+1)=round(P4),P4,(O4+1)&"-"&P4)),IF(U4="Max-1",If(K4>1,IF(round(O4)=round(P4-1),O4&" per Channel",O4&"-"&(P4-1)&" per Channel"),IF(round(O4)=round(P4-1),P4,O4&"-"&(P4-1)))))))
I then use this function to display a list of all the drivers that will work, but the result of the previous formula, even though it displays on the formulas sheet, will not display on the forms sheet.
=IFERROR(if($C$3="Y",if(BFFormulas!R1="CC",query(BFFormulas!A3:Z900,"select A,B,D,H,I,K,Q,L where A != '' and J='Y' and N = 'Y' order by D ",1),if(BFFormulas!R1="CV",query(BFFormulas!A3:Z900,"select A,B,D,H,I,K,Q,L where V > "&BFFormulas!T1*D3&" and A != '' and J='Y' order by D ",1),"Missing Fixture Information")),if(BFFormulas!R1="CC",query(BFFormulas!A3:Z900,"select A,B,D,H,I,K,Q,L where A != '' and N = 'Y' order by D ",1),if(BFFormulas!R1="CV",query(BFFormulas!A3:Z900,"select A,B,D,H,I,K,Q,L where V > "&BFFormulas!T1*D3&" and A != '' order by D ",1),"Missing Fixture Information"))),"Could Not Find Fixture From This Source.")
Can anyone tell me why this is happening?

Answer
QUERY will convert columns with mixed data types into one data type. If the data is mostly numerical values, then text strings (eg 1-2 in your data) will be converted to blank cells.
A workaround is to convert everything to text strings (if the consequences of that are acceptable to you). Note the &"" appended to each range in the QUERY functions.
=ArrayFormula(IFERROR(if($C$3="Y",if(BFFormulas!R1="CC",query(BFFormulas!A3:Z900&"","select A,B,D,H,I,K,Q,L where A != '' and J='Y' and N = 'Y' order by D ",1),if(BFFormulas!R1="CV",query(BFFormulas!A3:Z900&"","select A,B,D,H,I,K,Q,L where V > "&BFFormulas!T1*D3&" and A != '' and J='Y' order by D ",1),"Missing Fixture Information")),if(BFFormulas!R1="CC",query(BFFormulas!A3:Z900&"","select A,B,D,H,I,K,Q,L where A != '' and N = 'Y' order by D ",1),if(BFFormulas!R1="CV",query(BFFormulas!A3:Z900&"","select A,B,D,H,I,K,Q,L where V > "&BFFormulas!T1*D3&" and A != '' order by D ",1),"Missing Fixture Information"))),"Could Not Find Fixture From This Source."))
