Liam, 5, of Beacon Heights, has a rare and incurable brain tumour called Diffuse Intrinsic Pontine Glioma (DIPG).
An appeal to raise £½m was launched by his family so money could be available for any treatments that might help him.
The colour yellow is being used for events because Liam is a big fan of the Minions characters from the Despicable Me films.
As part of the Forge Trust we were keen to support the family of a colleague. We have very successfully raised nearly £300. Thank you to everyone who took part and contributed.
