Duvida sistema desenvolvido em silex/php

Pessoal, preciso de ajuda na seguinte questão.
Tenho um sistema de afiliados desenvolvido em silex/php, porem esta apresentando alguns erros, e não responde conforme o esperado.

Como deveria funcionar:
Ao indicar alguém, o indicador deveria ganhar 10% do valor do plano do indicado.

Rotina do sistema:
1º - Preenche o formulário do novo indicado ( dados pessoais, bancarios etc )
2º - No final do cadastro, tem um form para escolher o plano;
3º - Do plano escolhido, o indicador recebera 10% que sera creditado na conta dele no site.

Como esta funcionando:
O sistema não credita os 10%.

Estou quebrando a cabeça pra resolver isso, porque não tenho muita experiência. Será que vocês poderiam me ajudar?

Resumindo: preciso que o sistema faça o seguinte calculo:

1 - Indiquei uma pessoa no plano de R$100,00
2 - O sistema me paga R$10,00 de comissão ( 10% sobre plano de 100,00 )
