Run Code on_click of a Tab in a Master/Detail Form Application

I have a Master Detail Form Application where I use the sc_master_value to update a field based on the SUM of values in the detail form.

All works great except that the field on my Master is of type currency and I would simply like to have the “$” appear to the left of the SUM.

I perform a sc_lookup in the on_load event of the master which formats the field as it should but as soon as I go to the tab containing the detail form and edit a value which impacts the SUM, I get the correct value just without the “$” symbol.

Thanks in Advance.

did you try currency field format? another hint why don’t you use it in field label?
just saying
