update two records

Hey developers,

I need some help. Can anyone tell me what the problem is with this interface? I cannot update two records using the same button.

a!localVariables(
  local!livret: rule!PBY_getLivertByUser(),
  local!accounts: rule!PBY_getoccountByUser(),
  local!transactionAmount: if(
    not(isnull(ri!record['recordType!{4af9711d-c31c-43ce-b28b-448102fcb3db}PBY virementInterne.fields.{16a63de7-fa2e-4180-ae25-b255d12f5d9f}montant'])),
    ri!record['recordType!{4af9711d-c31c-43ce-b28b-448102fcb3db}PBY virementInterne.fields.{16a63de7-fa2e-4180-ae25-b255d12f5d9f}montant'],
    0
