Creatures Caves

Can someone tell me why these parts of my code show up as red syntax errors, please?

*install invisible flag agent:
new: simp 1 205 14868 "blnk" 0 0 9000

*this is the script that the patch core will trigger when it's time to spawn a flower:
setv name "spawn_script" 1000

*sprite image file and frame when the plant is fully grown:
sets name "sprite_file" "eggstravaganza"

* Randomly choose one of the 241 frames
* 240 in the command for 241 eggs, since it starts counting by 0
setv name "sprite_pose" rand 0 240

* offset the generic growing sprites, so they do not get picked as ripe frame
addv name "sprite_pose" 10

*classifiers:
setv name "prod_fmly" 2
setv name "prod_gnus" 11
setv name "prod_spcs" 14868

***set va00 to targ, enumerate all the instances of the patch core agent, send a message to that patch core agent that script 1000 is being targetted:
seta va00 targ
enum 1 1 22929
mesg wrt+ targ 1000 va00 0 0
next

*spawn:
scrp 1 205 14868 1000
inst

* Randomly choose one of the 241 frames
* 240 in the command for 241 eggs, since it starts counting by 0
setv va00 rand 0 240

* offset the generic growing sprites, so they do not get picked as ripe frame
addv va00 10

new: simp 2 7 14868 "eggstravaganza" 1 va00 name "patch_plane"

*flower properties:
*attr 80 = growth stages invisible to creatures so they won't be picked up, and don't want them to suffer physics just yet:
attr 80
bhvr 32
accg 2
perm rand 40 60
elas 20
aero 1
fric 100

*move to co-ords sent by the core patch agent:
mvto _p1_ _p2_

setv name "patch_id" mame "patch_id"
*replaced the "tick rand mame" and tick condition sections with this. We need to know the exact TICK because of what we'll be doing later. Originally the default was 500 ticks = about 25 seconds. We're going to set it to run about once every second.
tick 20

*and this is going to be our counter. We don't need to set a variable to zero, but I wanted to make a point to mention it now since we'll be using it later on.
setv ov95 0

targ ownr
slow
endm

*timer:
scrp 2 7 14868 1001

*age it every tick:
addv ov00 1

*if it's not fully grown, grow it to the next stage (only on every other tick):
doif ov00 le 16
doif ov00 eq 1
elif ov00 eq 3
elif ov00 eq 5
elif ov00 eq 7
elif ov00 eq 9
elif ov00 eq 11
elif ov00 eq 13
elif ov00 eq 15
else
setv va00 pose
addv va00 1

*if it is fully grown, make sure creatures can see/grab it.
attr 67
stop
pose va00
endi
endi

*added 7 steps to the growth process so make number 37, instead of 30, so eggs have more time before rotting:
*EDIT THIS if you want it to rot sooner/later. Smaller number = sooner.
elif ov00 gt 25

*if it's older then 20 ticks, let it rot. Fully rotten frame is 10:
doif pose eq 10
kill targ
endi
endi

*no intermediate sprites, has a closed 'night' sprite instead, so just set pose as 10:
pose 10

*if it's fully grown and has been sitting on the plant for 10 turns, it should fall off the patch. Added 7 steps, so number is 21 instead of 14:
*EDIT THIS if you want it to become grabbable sooner/later.
elif ov00 eq 17
doif attr eq 67
setv name "patch_id" 0
attr 195
stop
endi
endi
endm

*pickup:
scrp 2 7 14868 4
inst
endm

*remove:
rscr

Thank you!
