Change field data type from 'link to other sheet'

Hi, I have mistakenly formatted a field as ‘link to other sheet’. I don’t seem to be able to change this. The text is grey, not black and the drop down menu won’t come up. How do I fix this?

Thanks.

Hi Brett,

You may click on the Form Tools button in the design mode and click the sheet name listed under link&load section.

Then, in the linking manager, please remove the linking via this method.
