@Dorcas_Kagoya As explained by Tracey this is not the place for support questions for Communiteq hosting. If you have any, please use the Support form in our control panel at https://controlpanel.communiteq.com/ .
Of course you can always ask questions about more generic issues here on meta but in that case you should not (need to) address them to me!
In this case, the answer to your question can be found here Create and configure custom user fields
@bloomexperiment Thank you for the mention!
