Error awk problem

i have an email list in file.txt with comma separated

line1 - FIELD1,pippo@gmail.com,darth@gmail.com
line2 - FIELD2,pippo@gmail.com,darth@gmail.com,sampei@gmail.com

Code:
output=(awk -F ',' -v var="$awkvar" '$1==var {print $2,$3,$4}' spreadsheet.txt)

but awk delete some letters at the beginning of the output

Code:
echo "$output"

ippo@gmail.com darth@gmail.com
pippo@gmail.com darth@gmail.com sampei@gmail.com

but if i remove $4

Code:
ouput=(awk -F ',' -v var="$awkvar" '$1==var {print $2,$3}' spreadsheet.txt)

echo "$output"

it is correct display for line1 but not for line2:

pippo@gmail.com darth@gmail.com
pippo@gmail.com darth@gmail.com

What am I doing wrong?

Where did you close the single quote that you opened at :

'$1==var ?

What is the content of your $awkvar variable ?

What is the content of your $awkvar variable ? (wouldn't you use ~ rather than == ? ... of course depending on what you have and what you need).
Did you export it ?
Did you make sure your input file does not contain some invisible character ?
(editing it in vi for example and using :set list, or using -v option of cat )

$awkvar is match with FIELD1, FIELD2, FIELD3
awk print line that is equal to $awkvar
input file is correct, i have check it with cat -v

How big is your input file ? ... a variable has a limited length

by the way did you try
Code:
output=$( ... )

instead of
Code:
output=( ... )

?

Please provide a full example of input and code you use
