We need to know more information of how you are structured. Do you have a table which matches the checkbox value and then also holds the container for the logo? Also, what version of FM are you using?
FM Pro 11
The tables are related but are you saying the field which contains the checkbox needs to be directly related?
Well you should really use unique, FM-generated, auto-enter IDs for relating all tables but if you have a logos table with two fields, one called Value (for example) with the A, B, C etc and one with the container with the logo, and if you relate them as:
MainTable::Checkbox = Logos::Value
... then you can place a portal across your layout (in whatever configuration you wish). You can place one-row portals if you wish horizontal placement, specifying in portal config row 1 (and 1 row), row 2 (and 1 row) and so on.
