Customize style of automation message

[ryanchan]

Hi there, would like to get help on the following

I would like to create an "I'm interested" button and redirect to WhatsApp. However the text message I wish to customise it according to the field they selected above. This is the link format I used:

"https://wa.me/60392128545?text=Hi%20Chup,%20I'm%20interested%20in%20licensing%20for%20the%20location..."{Location Name}"

Error: Sorry, there was a problem saving this field. Invalid formula. Please check your formula text.

I would like my viewers to hit the button and send a WhatsApp message of "Hi Chup, I'm interested in licensing for the location of [Location Name Field]
