How to use the if condiation sentence in the docx template? example:

if(condiation==1){
    {{displayA}}
}else if(condiation==2){
    {{displayB}}
}else{
    {{displayOthers}}
}

hi! this looks like a handlebars question, when in doubts always make sure to search the handlebars docs.

to solve your issue you can define the following in your template helpers

function compare (a, b) {
  return a === b
}

then the usage in the docx should be like this

{{#if (compare condiation 1)}}
  {{displayA}}
{{else}}
  {{#if (compare condiation 2)}}
    {{displayB}}
  {{else}}
    {{displayOthers}}
  {{/if}}
{{/if}}

@bjrmatos
My template like this:
{{#docxList Projects}}
{{ClientName}} {{ClientAddress}}
{{ZipCode}}, {{ClientCity}}
{{ClientEmail}}
{{ClientPhone}}

{{#docxList CheckLists}}
{{#if Level==1}}
{{NodeNumber}} {{ChecklistName}} Utförd av: Datum:
{{else}}
{{NodeNumber}} {{ChecklistName}}
{{/if}}
{{/docxList}}
{{/docxList}}

I get a error as below:
{"message":"Error while executing docx recipe. Error while executing templating engine. Parse error on line 12:\n...Pr><w:t>{{#if Level==1}}</w:t></w:r><w:b\n-----------------------^\nExpecting 'OPEN_SEXPR', 'ID', 'STRING', 'NUMBER', 'BOOLEAN', 'UNDEFINED', 'NULL', 'DATA', got 'EQUALS'","stack":"Error: Error while executing docx recipe.

How to fix this error?

Hi!

to be clear, in the previous reply i've tried to show you how to do condition checks in handlebars, conditions like this Level==1 does not work in handlebars, you need to replace that part with a helper, exactly like i was showing you in my last reply. the error is about trying to parse invalid handlebars syntax so you need to change the way you do the conditions checks.
