Checkbox and IIF to set criteria for a field help

[offie]

So I have a field where the values start with either 4 or M and I want to be able to check which ones I want in a form, so far I have



Like IIf([Forms]![COSum]![4Check]=True,"4*",Null) And IIf([Forms]![COSum]![MCheck]=True,"M*",Null)

but it doesn't seem to workm, what am I doing wrong?

Thanks!

Nevermind,

Like IIf([Forms]![COSum]![4Check]=True,"4*",Null) Or Like IIf([Forms]![COSum]![MCheck]=True,"M*",Null)
