problem in attachment

2. Relevant equations

F= MA

3. The attempt at a solution

for m2: F= ma = T + m3g - m2g

T = -m3g + m2g

for m1: T = m1a

a = T/m1

plug in: a = (-m3g + m2g)/ m1

All 3 blocks: F = (M + m1 + m2 + m3)a

final answer: F = (M + m1 + m2 + m3)[(-m3g + m2g)/ m1]

So yea, I'm thinking this is wrong. Any advice on how to solve this would be appreciated.
