Logic

Logic is important to make your forms smart and conversational. The signature block can work with the following branch conditions to help you with that:

Block conditions

• Signed;
• Not signed.

Evaluate conditions

Evaluate conditions are done with the signature file name, which is a fixed file name in this format: signature-YYYYMMDDHHMMSS.png.

• Value matches your filter;
• Value does not match your filter;
• Value contains your filter;
• Value does not contain your filter;
• Value starts with your filter;
• Value ends with your filter;
• Value is empty;
• Value is not empty.

Filters

When we mention your filter above, there are some different filters that you can use to make the right comparison:

• Text - Compare with a fixed text that you enter;
• Value - Compare with another block value entered in the form by a respondent (more info).

Calculations

You can use the calculator block to perform calculations with given answers. For the signature block these calculations are done using the signature file name, which is a fixed file name in this format: signature-YYYYMMDDHHMMSS.png. The signature block supports the following calculation operations:

• Compare - Compare a file name and output a value based on the result of the comparison;
• Character count - Count the number of characters in a file name;
• Word count - Count the number of words in a file name;
• Line count - Count the number of lines in a file name;
• Count occurrences - Count the number of occurrences of a certain text, character or regular expression in a file name;
• Convert to number - Convert a file name to a number value.
