"Object of class Drupal\Core\Render\Markup could not be converted to number"

in flag

I am receiving an error on a webform I'm developing. Just to give some insight into the webform, the webform is taking in some data (customer type and monthly water consumption) and calculating the cost for Water, Solid Waste, and Sewer. I'm using computed twigs to calculate those cost, and I'm displaying them on the form. (This is where things get complicated). I am displaying current costs and new costs because we'll be applying a new percentage rate. So the user will be able to see current and new costs for Water, Solid Waste, and Sewer. All of this is working.

Now where I'm getting the error is calculating Final Current Cost and Final New Cost. (Basically, the Final Bill, adding Water, Solid Waste, and Sewer to get the Final Bill). I'm using a computed twig for Final Current Bill and Final New Bill.

I am just trying to add

{{ data.current_water_bill + data.current_wastewater_bill + data.current_solid_waste_bill }}

to get Final Current Bill.

But I'm receiving this error:

Notice: Object of class Drupal\Core\Render\Markup could not be converted to number in __TwigTemplate_b425658712bf48861094edd9faa7ac1869e3493432f58af037adf7477e731085->doDisplay() (line 39 of /tmp/rolling/26f07ce/twig/6255afcf3e700___string_template__3115aa_bPBQWZ4Ws1n7j52GBOzrbmeqE/rL677g5Ips8i5OfG_zSuLsRcL3s-sFwxT2_H3MJmsfo.php).

Provide details and any research I've dedicated some time into the error looking for the same error online. I've found a mixture of issues, but ultimately it looks like I need to convert the data into a number. I tried doing so using a twig filter |number_format and then I get a new error:

Notice: Object of class Drupal\Core\Render\Markup could not be converted to float in twig_number_format_filter() (line 611 of /code/vendor/twig/twig/src/Extension/CoreExtension.php).

I can calculate and display the values but I just can't add them. I've added the data into variables and still can't work with them in twig. Any ideas or suggestions would be appreciated.

Similar question https://drupal.stackexchange.com/questions/300862/total-of-multiple-computed-elements. But you have an error message that they didn't mention. To get rid of that you could try the `|render` filter to convert the markup object to a string. Then you can try to append other twig filters to get rid of html tags and currency signs until the string evaluates to a number.

Try passing the values through the |trim filter first, to cast them to strings.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
