[HELP] iMacros Script FB

Hi, i'm trying to create a script for FB Auto Comment. The script will go to every link in '.csv' file and leave a comment. See the picture below.

VERSION BUILD=8920312 RECORDER=FX
SET !ERRORIGNORE YES
SET !REPLAYSPEED MEDIUM
SET !DATASOURCE C:\Users\UserName\Desktop\Ads\fbadslinks.csv
SET !DATASOURCE_COLUMNS 1
SET !LOOP 1
SET !DATASOURCE_LINE {{!LOOP}}

TAB T=1
URL GOTO={{!COL1}}

SET !EXTRACT NULL
TAG POS=1 TYPE=form ATTR=CLASS:commentable_item<SP>autoexpand_mode EXTRACT=HTM
Set !VAR4 Eval("var exp = '{{!EXTRACT}}'.match(/ id=.(.*?)\" /); exp[1];")

SET !EXTRACT NULL
TAG POS={{!LOOP}} TYPE=DIV ATTR=CLASS:UFIAddCommentInput_1osb_5yk1
TAG POS={{!LOOP}} TYPE=UL ATTR=CLASS:UFIAddCommentInput_1osb_5yk1 EXTRACT=HTM
Set !VAR1 Eval("var exp = '{{!EXTRACT}}'.match(/UFICommentPhotoIcon.(.*?)class/); exp[1];")
Set !VAR1 Eval("var exp = '{{!VAR1}}'.match(/data-reactid=.(.*?)\"/); exp[1];")
TAG POS=1 TYPE=i ATTR=data-reactid:{{!VAR1}}

SET !EXTRACT NULL
TAG POS={{!LOOP}} TYPE=textarea ATTR=title:Write<SP>a<SP>comment...
TAG POS={{!LOOP}} TYPE=textarea ATTR=title:Write<SP>a<SP>comment... EXTRACT=HTM
Set !VAR3 Eval("var exp = '{{!EXTRACT}}'.match(/ id=.(.*?)\"/); exp[1];")

WAIT SECONDS=3
TAG POS={{!LOOP}} TYPE=textarea ATTR=title:Write<SP>a<SP>comment... CONTENT="Up Post!"
EVENTS TYPE=KEYPRESS SELECTOR="#{{!VAR3}}" KEYS="[13]"

I think i messed up somewhere in the script.

Specs:
- Win 7 64bit
- Firefox iMacros Addon (version 8920312)

Thanks.
