How can I add a dropdown menu to a single line text Form?

[Anonymous]

As seen on the picture attached. I'm trying to add a measure unit dropdown menu on a single line text form, as we're working with SharePoint. But on the corresponding Card settings (in this case the PS1 Card), I tried to modify the "Update" parameter from just "DataCardValue29.Text" to:

DataCardValue29.Text + MenuVoltaje30.SelectedText

I also tried adding MenuVoltaje30.Selected, of course with DataCardValue29 being the text box which in the picture has 220 written, and MenuVoltaje30 the dropdown menu on the right side.

My idea is for the user to only enter a number and then just select the corresponding voltage measure unit on the dropdown menu, but I have no idea how to concatenate and store both of these things on SharePoint. The error diagnostic says:

"Invalid argument type, one of the following expected: Number, Text, Boolean"

Thanks in Advance 🙂

hi, + is for calculations, try using & e.g.

DataCardValue29.Text & " " & MenuVoltaje30.SelectedText

If you are trying to concate them then

DataCardValue29.Text & MenuVoltaje30.SelectedText

If you are trying to add them:

Value(DataCardValue29.Text) + Value(MenuVoltaje30.SelectedText)
