call a function of subform from the main form

[Jerry Qu]

Trying to work around the problem with the previous post. I just found I can
not call public sub(function) of subform from the main form too:


in the subform

Public Sub fillData(strSQL as String)

msgbox strSQL

.....

end sub


in the main form:


Me!subfrmControlName.form.fillData strSQL
get error....




but it works fine without parent/child relation:


forms!subformName.fillData strSQL


please help

TIA
