The error occurs in line 146 in the METHODS function. I am getting the following error message.

INVALID EXPRESSION. CHECK FOR MISSING MULTIPLICATION OPERATOR, MISSING OR UNBALANCED DELIMITERS, OR OTHER SYNTAX ERROR. TO CONSTRUCT MATRICES, USE BRACKETS INSTEAD OF PARENTHESES.

While I was trying to edit the line in the code view of the APP DESIGNER, that particular line is disabled. As a result, I am not allowed to edit the code.

Any help would be appreciated. Thank you.

[Walter Roberson]

Your updateimage function is not within a methods section.

[Warid Islam]

Hi Walter,

Can you give me some suggestions about how to put the updateimage function in the METHODS section.

[Walter Roberson]

Move it to after "function delete" if you want it to be a user-accessible method.

[Warid Islam]

Hi Walter,

I am unable to edit any code after FUNCTION DELETE as that portion is gray which is not allowing me to do anything.

[Warid Islam]

Hi Walter,

Please take a look at the codes below. The METHODS part and the FUNCTIO DELETE part are gray in color which doesn't allow me to edit the code. Any suggestions would be appreciated. Thank you.

[Walter Roberson]

I suggest you open a technical support case. I have no experience with App Designer.

[Warid Islam]

Hi Walter,

Thank you.
