Controls on Form not supporting common properties

Hello all,
I’m working on a project in Visual Basic 6. My issue is that for some very strange reason some of the controls on a particular form are not supporting their usual propeties, e.g my checkbox is not supporting the ‘value’ property, therefore i cannot programmatically set it to ‘uncheck’ after a condition is satisfied. Instead i’m seeing ‘count, item, LBound and UBound’ from intelesense. Any idea why this is occurring?
Any help would be greatly appreciated.
