Patch combobox to sharepoint list error

[TM3K]

Dear community

I have checked similar messages regarding this topic, but could not rectify my error.

A combo box contains different selectable items. 

Patch( 'Trial Application List', Lookup( 'Trial Application List', ID = varCurrentItem ), { Product: ComboBox1_1.SelectedItems} )

The list, the ID and also the column "Product" are correct. However, it always throws the error:

Here my sp list colum details:

Thank you!

Hello @TM3K 

Are you sure varCurrentItem has data at the time of the patch?

Please use a label to verify this.

Hello @Jcook 

Yes, varCurrentItem is set OnSelect in the BrowseGallery. I use the ID for other references, too.

What do you mean with "please use a label to verify this?"
