dlvo potential-colloid modeling

Hello
When I use from
“pair_style hybrid/overlay colloid 25 yukawa/colloid 2.0 25
pair_coeff 1 1 colloid 39.478 1.0 10.0 10.0 25
pair_coeff 1 2 colloid 75.398 1.0 10.0 0.0 9
pair_coeff 2 2 colloid 144 1.0 0.0 0.0 2.5
pair_coeff 1 1 yukawa/colloid 100.0 “

to present DLVO potential to colloid modeling, I get this error:

Overlapping small/large in pair colloid pair_colloid.cpp:142 OR
Overlapping large /large in pair colloid pair_colloid.cpp:180

Can you help me to solve this problem?
Thanks in advance

It means that you have one or more pairs of overlapping particles.
The colloid potential is infinite at overlap, so this is an error. If
it happens immediately, you have a bad initial config. If it happens
after you run a while, you have bad dynamics.
